—Mysterious 'zombie planet' Halla seems to have survived the explosive death of its star. How? —Mirror-like exoplanet that 'shouldn't exist' is the shiniest world ever discovered —Star system with galaxy-like 'arms' may be holding a secret planet "There are planets that we've measured...
Jupiter, the largest planet in our solar system, is one of the most interesting. It was named after Jupiter, the most important Roman god. Nicknamed “King of Planets”, it is the fifth planet from the Sun and the fourth brightest object in the sky. Before the invention of the telescope...
The ELT will also be adept at studying planet formation in dusty disks around young stars and, with its Mid-infrared ELT Imager and Spectrograph (METIS), could even detect moons forming around planets. In addition, the ELT will probe star formation — not only in the present but also in ...
an atmospheric phenomenon caused when trace particles and gasses in the atmosphere become electrically charged or ionized. The atoms emit light at various wavelengths when they recombine at night and faintly glow. On the lower left side of the “planet” is the Vera C. Rubin...
The citizen science project Backyard Worlds: Planet 9 enlists the general public’s help in finding a possible ninth planet in our Solar System, by searching for moving objects in the data. Participants have already discovered new cool worlds in the vicinity of the Sun — objects mo...
Galaxy clusters, known as the largest self-gravitating objects in the universe, are home to a vast expanse of high-temperature gas. This gas emits brilliant X-rays, making these clusters visible. When these colossal clusters merge, it culminates in an astronomical event of unmatched magnitude, ...
Sites in the Southern Hemisphere were chosen to be the locations of the SKA Observatory because they have a clear view of the entirety of the Milky Way, as well as views out into intergalactic space. In contrast, from more northerly countries such as the U.K., the core of our galaxy ba...
(because it reached the southern horizon as seen in Hawai'i). The bright band extending from top to bottom is our Milky Way galaxy. The center of the galaxy is near the bottom edge of the image where the galaxy is brightest. In total, Pan-STARRS catalogued more than 800 million ...
In our 13.8 billion-year-old universe, most galaxies like ourMilky Wayform gradually, reaching their large mass relatively late. But a new discovery made with theAtacama Large Millimeter/submillimeter Array (ALMA)of a massive rotating disk galaxy, seen when the universe was only ten per...
To be housed in a building 22 stories high, out in the Atacama Desert of Chile, the GMT will be the largest optical telescope ever built.
