    The James Webb Telescope, operational for two years, has delivered remarkable space images, revealing mysteries like unexpected slumbering galaxies and discrepancies in the Hubble constant measurements. It has allowed astronomers to explore cosmic beauty, such as the Pillars of Creation, detailed by combining Webb's infrared and Hubble's visible spectrum data. These images, visible in both spectrum forms, advance our understanding of cosmic structures and star formation, highlighting the Pillars' complex makeup. The Serpent's Nebula "family portrait" further exemplifies Webb's capabilities, exposing young stars and nebula intricacies, previously unseen with older telescopes.

  • 00:05:00 - 00:12:31

    While a snapshot from NASA revealed young stars' outflow structures, new exoplanetary discoveries like the detection of Super-Jupiter Epsilon Indi Ab demonstrate Webb's contributions. Epsilon Indi Ab, a massive exoplanet in a unique star system just 12 light-years away, displays unusual characteristics and an eccentric orbit. This discovery corrects past errors in mass and orbit projections and provides an opportunity to compare with Jupiter, being much larger and older. Investigating aged exoplanets like Epsilon Indie Ab aids in testing planetary development theories and understanding late-stage planets, although unexpected phenomena, like radiation suppression, demand further study.

    the James web telescope has been
  • 00:00:09
    providing us with spectacular images
  • 00:00:11
    from space for 2 years now and while the
  • 00:00:14
    most powerful Space Telescope of all
  • 00:00:16
    time has been peering into the deepest
  • 00:00:18
    and oldest secrets of the cosmos it has
  • 00:00:21
    not only provided astronomers with many
  • 00:00:23
    groundbreaking insights but also a
  • 00:00:26
    number of tantalizing mysteries for how
  • 00:00:29
    can it that galaxies are slumbering out
  • 00:00:32
    there which according to our
  • 00:00:34
    understanding should not exist at all
  • 00:00:36
    why does the value of the Hubble
  • 00:00:38
    constant measured by web which describes
  • 00:00:40
    the expansion rate of the universe
  • 00:00:43
    simply not match our current models well
  • 00:00:46
    these are questions to which experts are
  • 00:00:49
    currently desperately searching for
  • 00:00:50
    answers fortunately the James web
  • 00:00:53
    telescope is not only capable of
  • 00:00:55
    uncovering the most baffling mysteries
  • 00:00:57
    of space but also its over whelming
  • 00:01:00
    almost frightening Beauty which
  • 00:01:02
    regularly reminds us how small we are in
  • 00:01:04
    the grand scheme of things humans like
  • 00:01:07
    to describe themselves as the crown of
  • 00:01:10
    creation whether we want to accept this
  • 00:01:12
    not exactly modest title is of course up
  • 00:01:15
    to each of us to decide for ourselves
  • 00:01:18
    but when it comes to the question of the
  • 00:01:20
    most impressive creators of the universe
  • 00:01:22
    it is clear who deserves the honor but
  • 00:01:25
    before we get it wrong the James web
  • 00:01:27
    telescope has of course not uncovered
  • 00:01:30
    some ominous power that created the
  • 00:01:32
    cosmos but together with Hubble has
  • 00:01:34
    provided an unprecedented combined view
  • 00:01:37
    of The Pillars of Creation which are
  • 00:01:39
    among the most famous photo motifs in
  • 00:01:42
    modern space exploration some 7,000
  • 00:01:45
    Lighty years away from us in the open
  • 00:01:48
    star cluster of the Eagle Nebula we are
  • 00:01:50
    looking at the glowing pillars of a
  • 00:01:52
    stellar cradle captured for the first
  • 00:01:55
    time by the hule Space Telescope
  • 00:01:57
    basically Stellar life begins in dense
  • 00:02:00
    cool clouds of gas and dust when the gas
  • 00:02:03
    clumps collapse under their own gravity
  • 00:02:05
    a protostar is formed first which
  • 00:02:08
    attracts matter from its immediate
  • 00:02:10
    surroundings and as soon as the
  • 00:02:12
    sparkling Offspring has built up enough
  • 00:02:15
    Mass it can ignite the hydrogen Fusion
  • 00:02:17
    in its interior and become a real star
  • 00:02:20
    however Stars often do not develop on
  • 00:02:23
    their own but in Collective alliances
  • 00:02:25
    such as the Pillars of Creation but
  • 00:02:28
    while the Hubble Cosmic snapshot sh from
  • 00:02:30
    1995 still shows the overwhelming
  • 00:02:33
    structure in the visible wave range the
  • 00:02:35
    James web telescope took a look at it in
  • 00:02:37
    the infrared the combination of these
  • 00:02:40
    two images ultimately gives us
  • 00:02:42
    completely new insights into this
  • 00:02:44
    structure whose fingerlike outgrowths
  • 00:02:46
    are even larger than our entire solar
  • 00:02:49
    system and while countless newborn Proto
  • 00:02:52
    stars and stars lie dormant in the dusty
  • 00:02:54
    cumner cocoons their intense radiation
  • 00:02:57
    and Stellar winds have blown gaping
  • 00:02:59
    holes into the dust cloud shells giving
  • 00:03:01
    them an unmistakable appearance given
  • 00:03:05
    this breathtaking sight it's no wonder
  • 00:03:07
    that The Pillars of Creation were among
  • 00:03:09
    the first subjects of the James web
  • 00:03:11
    telescope in
  • 00:03:12
    2022 but now NASA has combined the
  • 00:03:15
    Hubble and web images to reveal even
  • 00:03:17
    more details while the infrared images
  • 00:03:20
    reveal the Stellar babies and cool gas
  • 00:03:23
    components the visible light presents
  • 00:03:25
    the scorching hot glowing gases of the
  • 00:03:28
    star Forge the bottom line is that the
  • 00:03:30
    spectacle is not only available as a
  • 00:03:32
    photo but also as a video if you watch
  • 00:03:35
    the corresponding clip you will be
  • 00:03:37
    treated to an exciting flight through
  • 00:03:39
    the threedimensional Pillars of Creation
  • 00:03:42
    in the course of this the view switches
  • 00:03:44
    between visible and infrared light
  • 00:03:47
    proving once again why it is so
  • 00:03:49
    important to explore the different
  • 00:03:50
    aspects of one and the same structure
  • 00:03:53
    with more than one Space
  • 00:03:55
    Telescope the Stellar family portrait
  • 00:03:59
    no less fascinating than the combined
  • 00:04:01
    view of The Pillars of Creation is the
  • 00:04:04
    family photo that Webb recently snapped
  • 00:04:06
    in the Serpent's nebula 1300 light years
  • 00:04:09
    away in detail we are also dealing here
  • 00:04:12
    with a stellar Nursery more precisely
  • 00:04:15
    with a so-called reflection nebula which
  • 00:04:17
    produces no light of its own but is
  • 00:04:19
    illuminated solely by the Light of the
  • 00:04:21
    stars in its interior and its vicinity
  • 00:04:24
    for the telescopes of the past the
  • 00:04:26
    nebuli were often still insurmountable
  • 00:04:28
    Optical barriers but web's near cam is
  • 00:04:31
    able to penetrate the dust and gas
  • 00:04:33
    compounds to a certain degree and thus
  • 00:04:36
    make visible those things that have
  • 00:04:38
    eluded our research vision for so long
  • 00:04:41
    and while the gas and dust in the images
  • 00:04:43
    are a vibrant orange red and blue we can
  • 00:04:46
    also see the intense Sparkle of the
  • 00:04:48
    countless young Stars some of these
  • 00:04:51
    dazzlingly bright celestial bodies are
  • 00:04:53
    just 100,000 years old which means they
  • 00:04:56
    are still in their infancy in
  • 00:04:58
    astronomical terms and yet one day they
  • 00:05:00
    will have the mass of our sun the bottom
  • 00:05:03
    line is that one detail of the Star
  • 00:05:05
    Family Portrait is particularly striking
  • 00:05:09
    the Flamel likee structures at the top
  • 00:05:11
    left of the image which are reminiscent
  • 00:05:13
    of colossal shreds these are the traces
  • 00:05:16
    of gas and radiation outflows from Young
  • 00:05:18
    Stars which appeared in earlier images
  • 00:05:21
    invisible light either as blurred spots
  • 00:05:24
    or even completely invisible NASA
  • 00:05:26
    Compares these Proto Stellar outflows to
  • 00:05:29
    sleep falling from the sky during a
  • 00:05:31
    strong storm and this is the first image
  • 00:05:33
    to show that the outflows all point in
  • 00:05:36
    the same direction but what for us are
  • 00:05:38
    merely structures moving from top left
  • 00:05:41
    to bottom right on the images are an
  • 00:05:43
    important research indication for the
  • 00:05:46
    experts after all this image evidence
  • 00:05:49
    supports the assumption that young Stars
  • 00:05:51
    tend to rotate in the same direction
  • 00:05:53
    when their gaseous birth envelopes
  • 00:05:55
    collapse but what's the story behind the
  • 00:05:58
    black bars at the bottom left and top
  • 00:06:00
    right of the image has NASA applied the
  • 00:06:02
    sensor pen here to make one or two UFOs
  • 00:06:06
    unrecognizable well unfortunately it's
  • 00:06:08
    not quite that exciting the black
  • 00:06:10
    rectangles simply indicate missing
  • 00:06:13
    data the first photo of the super
  • 00:06:17
    Jupiter
  • 00:06:19
    6,911 exoplanets in
  • 00:06:21
    4,941 systems the number of known
  • 00:06:24
    planetary worlds orbiting a host star
  • 00:06:27
    other than the sun is growing
  • 00:06:28
    practically by the day
  • 00:06:30
    researchers have already added some
  • 00:06:32
    unusual celestial bodies to the star
  • 00:06:34
    Maps as part of the planet hunt so far
  • 00:06:37
    these include for example the gas giant
  • 00:06:40
    hd189733b
  • 00:06:42
    which is only 63 light years away and
  • 00:06:45
    according to the latest findings smells
  • 00:06:48
    like rotten eggs but what initially
  • 00:06:50
    sounds rather strange or amusing is
  • 00:06:53
    actually the first evidence of hydrogen
  • 00:06:55
    sulfide on an extra Solar Planet apart
  • 00:06:58
    from this the expert have also proved to
  • 00:07:01
    have the right nose in other areas
  • 00:07:03
    because we now know of a whole series of
  • 00:07:06
    nearby exoplanets some of which are
  • 00:07:08
    earth-sized and even potentially
  • 00:07:10
    life-friendly in this Regard
  • 00:07:13
    k218b in particular has been making
  • 00:07:15
    headlines for several months because
  • 00:07:18
    this Celestial body is actually
  • 00:07:20
    suspected of being a full-blown Ocean
  • 00:07:22
    World on which life may even have
  • 00:07:25
    already unfolded in detail web's near
  • 00:07:28
    infrared spectrometer near speec
  • 00:07:30
    captured some potential bio signatures
  • 00:07:32
    here specifically the spectral
  • 00:07:34
    signatures of methane carbon dioxide and
  • 00:07:37
    dimethyl sulfide or DMS for short the
  • 00:07:40
    latter is produced on Earth by Marine
  • 00:07:42
    Plankton and during the decomposition of
  • 00:07:44
    organic substances the molecule is the
  • 00:07:47
    main supplier of atmospheric sulfur and
  • 00:07:50
    produces the typical Marine odor how the
  • 00:07:53
    DMS signal on k218b is to be interpreted
  • 00:07:57
    however is a completely different matter
  • 00:07:59
    in fact it was not particularly
  • 00:08:01
    pronounced in the web data and only
  • 00:08:03
    revealed itself when the data sets were
  • 00:08:05
    analyzed in a very special way so until
  • 00:08:08
    the background to this exciting
  • 00:08:10
    Discovery is fully clarified a little
  • 00:08:12
    patience is still required but things
  • 00:08:15
    look a little different in the case of a
  • 00:08:17
    snapshot that web took in a completely
  • 00:08:19
    different place despite all the
  • 00:08:21
    exoplanets that have already been
  • 00:08:23
    discovered different images of these
  • 00:08:25
    alien worlds are still in short supply
  • 00:08:28
    most Imes mainly show young hot gas
  • 00:08:31
    giants after all these appear as
  • 00:08:34
    comparatively bright spots on the light
  • 00:08:36
    in the infrared but there is a much
  • 00:08:38
    cooler way a few weeks ago Elizabeth
  • 00:08:41
    Matthews and her team from the max plank
  • 00:08:43
    Institute for astronomy in heidleberg
  • 00:08:45
    succeeded for the first time in making a
  • 00:08:48
    cold older exoplanet directly visible
  • 00:08:51
    the foundation for the image was laid by
  • 00:08:53
    studying the triple star system Epsilon
  • 00:08:55
    Indie which is located just 12 light
  • 00:08:58
    years away from us and while the cosmic
  • 00:09:00
    Trio is made up of two brown dwarfs and
  • 00:09:03
    the orange dwarf star Epsilon India
  • 00:09:06
    earlier spectral analysis had already
  • 00:09:08
    indicated the existence of a large
  • 00:09:10
    planetary companion an analysis with
  • 00:09:13
    web's Miry spectrograph later revealed
  • 00:09:15
    that the system did indeed Harbor an
  • 00:09:18
    exoplanet but it was in a completely
  • 00:09:20
    different location than the earlier
  • 00:09:21
    studies had suggested the simple reason
  • 00:09:24
    for this was that the previous studies
  • 00:09:26
    had hopelessly underestimated the mass
  • 00:09:29
    and orbit of this Giant gas planet
  • 00:09:32
    because the bottom line is that we are
  • 00:09:33
    dealing here with a Celestial body that
  • 00:09:36
    can confidently be described as a super
  • 00:09:38
    Jupiter we remember as the largest
  • 00:09:40
    member of our planetary System Jupiter
  • 00:09:43
    has a diameter of around 140,000 km and
  • 00:09:46
    a mass of 318 Earth masses however the
  • 00:09:50
    bright point of light that the experts
  • 00:09:52
    detected in the images of Epsilon Indie
  • 00:09:55
    is probably six times the mass of our
  • 00:09:57
    Jupiter christened Epsilon Indie a-b the
  • 00:10:01
    extrasolar Colossus orbits the main star
  • 00:10:04
    Epsilon Indie a in a relatively
  • 00:10:06
    eccentric orbit the greatest distance of
  • 00:10:08
    which corresponds approximately to the
  • 00:10:10
    distance between the Sun and Neptune as
  • 00:10:13
    a result of this constellation super
  • 00:10:15
    Jupiter takes a whopping 200 years to
  • 00:10:18
    complete a full orbit and it was in fact
  • 00:10:20
    this eccentric orbit that explained the
  • 00:10:22
    surprising deviations in earlier
  • 00:10:25
    observations this is because they had
  • 00:10:27
    actually detected the planet at the
  • 00:10:29
    closest point to the star in its orbit
  • 00:10:32
    and in the same breath incorrectly
  • 00:10:34
    located it in a circular orbit however
  • 00:10:37
    the new analysis was not only
  • 00:10:39
    accompanied by an orbit correction but
  • 00:10:41
    also revealed some of the exoplanets
  • 00:10:43
    characteristics for example the
  • 00:10:45
    thermometer here drops to around 0° on
  • 00:10:48
    average and with an age of around 3.5
  • 00:10:51
    billion years the gas giant is truly no
  • 00:10:54
    longer a planetary youngster of the 25
  • 00:10:57
    or so exoplanets directly IM so far all
  • 00:11:00
    were less than 500 million years old the
  • 00:11:03
    majority had less than 100 million years
  • 00:11:05
    under their belt against this background
  • 00:11:08
    Epsilon India a-b is therefore not only
  • 00:11:11
    the coldest but also by far the oldest
  • 00:11:14
    exoplanet that has been directly imaged
  • 00:11:16
    to date the corresponding images are of
  • 00:11:19
    course not only beautiful to look at for
  • 00:11:22
    the scientists they also hold huge
  • 00:11:24
    potential for gaining new insights for
  • 00:11:27
    example aged exoplanets of this kind are

    ideal for putting our models of

    later stages of extrasolar Worlds at the
  • 00:11:39
    same time however Epsilon Indie a-b
  • 00:11:42
    still holds a few mysteries in store for
  • 00:11:45
    it appears that parts of its radiation
  • 00:11:47
    in the shorter wavelength range are
  • 00:11:49
    literally being swallowed up there may
  • 00:11:52
    be clouds in the gas giants atmosphere
  • 00:11:54
    that are responsible for absorbing the
  • 00:11:56
    infrared radiation although chemical
  • 00:11:58
    compound compounds such as methane
  • 00:12:00
    carbon dioxide and carbon monoxide are
  • 00:12:03
    also possible causes conveniently the
  • 00:12:06
    experts are already planning to
  • 00:12:08
    investigate the consequences and
  • 00:12:09
    provided nothing unforeseen happens the
  • 00:12:12
    true reasons for the suppressed
  • 00:12:13
    radiation flux will soon be clarified
