When is a star not a star?
Sep 18, 2018 (SPX)
To shine bright, stars need the energy derived from the fusion of hydrogen atoms deep in their interiors. If too small, hydrogen fusion can't occur, so the obje...
TESS Shares First Science Image in Hunt to Find New Worlds
Sep 18, 2018 (SPX)
"In a sea of stars brimming with new worlds, TESS is casting a wide net and will haul in a bounty of promising planets for further study," said Paul Hertz, astr...
SwRI scientists find evidence for early planetary shake-up
Sep 11, 2018 (SPX)
These bodies, called Patroclus and Menoetius, are targets of NASA's upcoming Lucy mission. They are around 70 miles wide and orbit around each other as they col...
New Exoplanet Discovered by Team Led by Canadian Student
Sep 10, 2018 (SPX)
Wolf 503b is about 145 light-years from Earth in the Virgo constellation; it orbits its star every six days and is thus very close to it, about 10 times closer ...
Youngest Accretion Disk Detected in Star Formation
Sep 07, 2018 (SPX)
This discovery poses a constraint on current theory of disk formation stronger than before, by pushing the disk formation time by a factor of a few earlier. Mor...
A Direct-Imaging Mission to Study Earth-like Exoplanets
Sep 06, 2018 (SPX)
The study of exoplanets - planets outside our solar system that orbit a star - has seen remarkable discoveries in the past decade. The report identifies two ove...
Little star sheds light on young planets
Sep 05, 2018 (SPX)
Early in 2017, Assistant Professor Yoko Oya gave graduate student Yuki Okoda some recent complex data on a nearby star with which she could begin her Ph.D. Litt...
Rutgers scientists identify protein that may have existed when life began
Sep 04, 2018 (SPX)
Their study of a primordial peptide, or short protein, is published in the Journal of the American Chemical Society. In the late 1980s and early 1990s, the chem...
Water worlds could support life, study says
Sep 03, 2018 (SPX)
The scientific community has largely assumed that planets covered in a deep ocean would not support the cycling of minerals and gases that keeps the climate sta...
Scientist develops database for stellar-exoplanet exploration
Aug 30, 2018 (SPX)
"At first scientists focused on temperatures, looking for exoplanets in the 'Goldilocks zone' - neither too close nor too far from the star, where liquid water ...
Infant exoplanet weighed by Hipparcos and Gaia
Aug 24, 2018 (ESA)
Astronomers Ignas Snellen and Anthony Brown from Leiden University, the Netherlands, deduced the mass of the planet Beta Pictoris b from the motion of its host ...
Discovery of a structurally 'inside-out' planetary nebula
Aug 20, 2018 (SPX)
The discovery of a structurally 'inside-out' planetary nebula - the ionized material that surrounds a white dwarf - was just reported online in Nature Astronomy...
Under pressure, hydrogen offers a reflection of giant planet interiors
Aug 20, 2018 (SPX)
Hydrogen is the most-abundant element in the universe and the simplest - comprised of only one proton and one electron in each atom. But that simplicity is dece...
Scientists discovered organic acid in a protoplanetary disk
Aug 17, 2018 (SPX)
'We have found formic acid in the protoplanetary disk surrounding the young sun-like star TW Hydra. The finding implies that rich organic chemistry, which can l...

Aug 16, 2018 (SPX)
Today, an international team, led by researchers from the University of Geneva (UNIGE), who joined forces with theoreticians from the University of Bern (UNIBE)...
Iron and Titanium in the Atmosphere of an Exoplanet
Aug 15, 2018 (SPX)
Scientist begins developing instrument for finding extraterrestrial bacteria
Aug 10, 2018 (SPX)
Although very early in its technology development, the concept would take NASA's hunt for extraterrestrial life to the next level by actually looking for bacter...
Omega Centauri unlikely to harbor life
Aug 10, 2018 (SPX)
Omega Centauri - a densely packed cluster of stars in our galactic backyard - is unlikely to be home to habitable planets, according to a study by scientists at...
Ultrahot planets have starlike atmospheres
Aug 10, 2018 (SPX)
