Hubble Finds Water Vapor On Distant Exoplanet

Using data from NASA’s Hubble and Spitzer Space Telescopes, astronomers have found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds,” where water makes up a large fraction of the entire planet.For more information, visit https://nasa.gov/hubble.

A star’s death throes have so violently disrupted its planetary system that the dead star left behind, called a white dwarf, is siphoning off debris from both the system’s inner and outer reaches. This is the first time astronomers have observed a white dwarf star that is consuming both rocky-metallic and icy material, the ingredients of planets. Archival data from NASA’s Hubble Space Telescope and other NASA observatories were essential in diagnosing this case of cosmic cannibalism. The findings help describe the violent nature of evolved planetary systems and can tell astronomers about the makeup of newly forming systems.For more information, visit https://nasa.gov/hubble.

Scientists using NASA’s Hubble Space Telescope have found evidence that a planet orbiting a distant star that may have lost its atmosphere but gained a second one through volcanic activity. The planet, GJ 1132 b, is hypothesized to have begun as a gaseous world with a thick hydrogen blanket of atmosphere. Starting out at several times the diameter of Earth, this so-called “sub-Neptune” is believed to have quickly lost its primordial hydrogen and helium atmosphere due to the intense radiation of the hot, young star it orbits. In a short period of time, such a planet would be stripped down to a bare core about the size of Earth. That’s when things got interesting.For more information, visit https://nasa.gov/hubble.

The Hubble Space Telescope has transformed our understanding of the universe, its view from orbit unleashing a flood of cosmic discoveries that have changed astronomy forever. From its discovery of dark energy to its quest to determine the age of the universe, Hubble has helped answer some of the most compelling astronomical questions of our time and revealed even stranger phenomena, opening our eyes to the grandeur and mystery of space.For more information, visit https://nasa.gov/hubble.Credit: NASA by Magnum Opus [ ASCAP ] Universal Production Music Master VersionHorizontal version.

The universe would be a pretty boring place without stars. Without them, the universe would remain a diffuse plasma of mostly hydrogen and helium from the big bang. To better understand stellar evolution, a new Hubble initiative has been launched called ULLYSES (UV Legacy Library of Young Stars as Essential Standards). This is the largest observing program ever undertaken by NASA’s Hubble Space Telescope, which will be used to look at over 300 stars. Ultraviolet (UV) light from the target stars will be used to produce a library of the spectral fingerprints of young, low-mass stars from eight star-forming regions in the Milky Way, as well as fully mature high-mass stars in several nearby dwarf galaxies including the Magellanic Clouds.For more information, visit https://nasa.gov/hubble.Music Credits: by Christian Tschuggnall [AKM] and Michael Edwards [APRA] via Atmosphere Music Ltd [PRS] and Universal Production Music Master VersionHorizontal version.

On April 24, 2020, the Hubble Space Telescope celebrated its 30th year in orbit by premiering a never-before-seen view of two stunning nebulas named NGC 2020 and NGC 2014. Even after all these years, Hubble continues to uncover the mysteries of the universe. These are a few science achievements from Hubble’s latest year in orbit.For more information about the Hubble Space Telescope and its images, visit https://nasa.gov/hubble.Music Credits:“Twist of Fate” by Axel Tenner [GEMA], Michael Schluecker [GEMA], and Raphael Schalz [GEMA].

Its size and surface gravity are much larger than Earth’s, and its radiation environment may be hostile, but a distant planet called K2-18b has captured the interest of scientists all over the world. For the first time, researchers have detected water vapor signatures in the atmosphere of a planet beyond our solar system that resides in the — exoplanets with masses between those of Earth and Neptune — found by Kepler. NASA’s TESS mission is expected to detect hundreds more super-Earths in the coming years. The next generation of space telescopes, including the James Webb Space Telescope, will be able to characterize exoplanet atmospheres in more detail.The Hubble Space Telescope is a project of international cooperation between ESA (the European Space Agency) and NASA.

Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of Earth-sized planets in the TRAPPIST-1 system Killer Tracks Production Music

On May 4th, 2016, the Hubble Space Telescope made the first spectroscopic measurements of two of the three known Earth-sized exoplanets in the TRAPPIST-1 system just 40 light-years away. Now the results are in: a thick, puffy, hydrogen-helium atmosphere is likely ruled out from the possible range of atmospheres for these two planets.Additional visuals from the European Southern Observatory can be downloaded here: http://www.eso.org/public/news/eso1615/E Watch this video on the NASA.gov Video YouTube channel.Music credit: by Louise Dowd and Stephen William Cornish, Atmosphere Music Ltd, Killer Tracks Production Music Animation - Artist concept of the double-transit Hubble observed on May 4, 2016, when planets TRAPPIST-1b and TRAPPIST-1c passed across the disk of their host star just minutes apart.

Using NASA’s Hubble Space Telescope, scientists have detected a stratosphere, one of the primary layers of Earth’s atmosphere, on a massive and blazing-hot exoplanet known as WASP-33b.The presence of a stratosphere can provide clues about the composition of a planet and how it formed. This atmospheric layer includes molecules that absorb ultraviolet and visible light, acting as a kind of “sunscreen” for the planet it surrounds. Until now, scientists were uncertain whether these molecules would be found in the atmospheres of large, extremely hot planets in other star systems.Learn more on NASA.gov. ANIMATION Using NASA’s Hubble Telescope, scientists detected a stratosphere on the planet WASP-33b. A stratosphere occurs when molecules in the atmosphere absorb ultraviolet and visible light from the star. This absorption warms the stratosphere and acts as a kind of sunscreen layer for the planet below.Watch this video on YouTube. ILLUSTRATION WASP-33b’s stratosphere was detected by measuring the drop in light as the planet passed behind its star (top). Temperatures in the low stratosphere rise because of molecules absorbing radiation from the star (right). Without a stratosphere, temperatures would cool down at higher altitudes (left).
