NASA Launches TESS the Exoplanet Hunter

April 23, 2018

The Transiting Exoplanet Survey Satellite, or TESS, will soon join NASA’s fleet of exoplanet-hunters that, so far, includes the Kepler, Hubble, and the Spitzer Space Telescopes. TESS was launched at 2251 UTC on April 18, 2018, from the Cape Canaveral Air Force Station in Florida. The space observatory is expected to survey about 85% of […]

Lots of Water Detected in Exoplanet WASP 39b Atmosphere

March 5, 2018

Scientists, who studied a “hot Jupiter-like” exoplanet with NASA’s Hubble and Spitzer space telescopes, were able to detect signs of water in its atmosphere. And, they didn’t just find signs of a little water – but a lot of water, three times the amount of water on our solar system’s largest planet, Jupiter. The exoplanet they […]

Astronomers Find Massive Star Making Galaxy Cluster

September 12, 2015

Astronomers have discovered a distant and massive galaxy cluster with a gigantic and prolific galaxy at its heart that’s pumping out hundreds of stars each year. The galaxy cluster is named SpARCS 1049+56 and is located about 9.8 billion light years from Earth in the Ursa Major constellation. Galaxy clusters are areas of the universe […]

The galaxy EGS-zs8-1 sets a new distance record. It was discovered in images from the Hubble Space Telescope from the CANDELS survey. (NASA, ESA, P. Oesch and I. Momcheva (Yale University), 3D-HST and HUDF09/XDF Teams)

Astronomers Detect a Galaxy Far, Far Away

May 6, 2015

Astronomers have discovered the most distant galaxy ever detected, gaining new insight into the early beginnings of our universe. Identified as EGS-zs8-1, the international team of astronomers measured its exact distance at 13 billion light years away from Earth. That means that light from the galaxy now reaching Earth was produced back when the universe […]

Coldest-Ever Brown Dwarf Star Discovered

April 28, 2014

The coldest-ever brown dwarf star has been found about 7 light-years away from Earth and could help scientist learn more about the atmospheres of planets. Brown dwarfs are objects that are too big to be planets, but too small to be considered stars.  They begin their lives like stars, but since their mass is so […]

Astronomers May Have Spotted A Moon Orbiting an Extrasolar Planet

April 11, 2014

According to NASA, more than 1,000 extrasolar planets have been confirmed in recent years. There are also thousands more potential planets beyond our solar system that are waiting to be discovered. Now, an international group of astronomers think they may have found the first exomoon, or moon circling an exoplanet, some 1,800 light years away […]

Astronomers Discover Furthest Galaxy Ever

November 16, 2012

Scientists have discovered what could be the oldest, most distant galaxy in the universe, thanks to a unique combination of man-made and natural telescopes. The newly discovered galaxy, MACS0647-JD, was found by the Cluster Lensing And Supernova Survey with Hubble (CLASH). It is about 13.3 billion light years, or 125,825,000,000,000,000,000,000 km, from Earth. Scientists are […]
