This Hubble Space Telescope picture shows NGC 5398, a barred spiral galaxy located about 55 million light-years away.
Using Hubble’s Space Telescope, researchers have found a planet so dark that it absorbs 94 percent of the light that reaches it. Read more...
NASA's Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. This light-eating prowess is due to the planet's unique capability to trap at least 94 percent of the visible starlight falling into its atmosphere.
Astronomers have discovered that the well-studied, egg-shaped exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b's atmosphere. The...

(Université de Genève) Astronomers from UNIGE), also members of the PlanetS, focused the Hubble Space Telescope on an exoplanet that had already been seen losing its atmosphere, which forms an enormous cloud of hydrogen, giving the planet the appearance of a giant comet. Show More Summary
Astronomers from the University of Geneva (UNIGE), Switzerland and collaborators used the Hubble Space Telescope to study an exoplanet that had been observed losing its atmosphere, forming an enormous cloud of hydrogen and giving the planet the appearance of a giant comet. Show More Summary
NIST scientists have achieved a world record in detecting the intensity of an ultra-faint source of light, equaling the capabilities of the deep-space instruments on the Hubble Space Telescope but operating 100 times faster and with equivalent accuracy.
A growing band of debris and tiny satellites imperils the Hubble Space Telescope and equipment used for phones, national security and weather forecasting. Officials worry the clutter might eventually make some parts of space unusabl...
Water could be present on some of the Earth-sized planets orbiting the dwarf star TRAPPIST-1, according to work from an international group of astronomers. They utilized the NASA/ESA Hubble Space Telescope to estimate substantial amounts of water could be present in the outer planets, including three in the habitable zone. This boosts the possibility those planets are livable.[...]
(ESA/Hubble Information Centre) An international team of astronomers used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the seven earth-sized planets orbiting the nearby dwarf star TRAPPIST-1. The results suggest that the outer planets of the system might still harbour substantial amounts of water. Show More Summary
A deceptively valuable wall hanging: this section of the NASA–ESA Hubble Space Telescope's solar array flew for eight years in space before being returned to Earth aboard a Space Shuttle, and is now displayed at ESA's technical centre in Noordwijk, the Netherlands.
NASA's James Webb Space Telescope will use its infrared capabilities to study the "ocean worlds" of Jupiter's moon Europa and Saturn's moon Enceladus, adding to observations previously made by NASA's Galileo and Cassini orbiters. "We chose these two moons because...
A new NASA TDRS satellite has headed into space where it will relay data from the International Space Station and Hubble Space Telescope. It may be the last one, though. The post NASA Beefs Up Space Communications with New Satellite Launch appeared first on ExtremeTech.
NASA launched the last of its longtime tracking and communication satellites on Friday, a vital link to astronauts in orbit as well as the Hubble Space Telescope.
NASA launched the last of its longtime tracking and communication satellites on Friday, a vital link to astronauts in orbit, as well as the Hubble Space Telescope. The end of the era came with a morning liftoff of TDRS-M, the 13th satellite in the Tracking and Data Relay Satellite network,...
The subject of this NASA/ESA Hubble Space Telescope image is a dwarf galaxy named NGC 5949. Thanks to its proximity to Earth—it sits at a distance of around 44 million light-years from us, placing it within the Milky Way's cosmic neighborhood—NGC 5949 is a perfect target for astronomers to study dwarf galaxies.
Size is entirely relative, so to say that the galaxy named NGC 5949 is "small" is a bit of a joke, especially once you've gotten an eyeful of this truly stunning snapshot taken by the Hubble Space Telescope. The swirling mass of gas,...Show More Summary
The Hubble Space Telescope may be old, but it's often still the best way for astronomers to observe distant objects. For example, the massive exoplanet WASP-121b orbiting a star roughly 900 light years from Earth. The post Hubble Observes Alien Planet’s Stratosphere for the First Time appeared first on ExtremeTech.
A planet with an atmosphere where water molecules glow is the strongest evidence yet of the first stratosphere discovered on a world outside the Solar System. Using data from NASA's Hubble Space Telescope, an international team of scientists...Show More Summary
