Scientists find an Earth-sized pi planet with a 3.14-day orbit
In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a "pi Earth" -- an Earth-sized planet that zips...
Jupiter’s moons may keep each other toasty
Interactions between Jupiter’s moons may bear more responsibility for their warm interiors than heating from Jupiter alone, researchers report.
Jupiter’s moons are hot.
Well, hotter than...
How planetary nebulae get their shapes
About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most...
Astronomers capture stellar winds in unprecedented detail
Astronomers present an explanation for the mesmerising shapes of planetary nebulae.
The discovery is based on an extraordinary set of observations of stellar winds around...
Astronomers may have found a signature of life on Venus
The search for life beyond Earth has largely revolved around our rocky red neighbor.
NASA has launched multiple rovers over the years, with a new...
Scientists find hints of life on Venus
A research team, led by Professor Jane Greaves of Cardiff University, today announced the discovery of a rare molecule - phosphine - in the...
Scientists discover a warm Jupiter orbiting a cool star
A planet observed crossing in front of, or transiting, a low-mass star has been determined to be about the size of Jupiter.
While hundreds of...
Jupiter’s moons could be warming each other
Jupiter's moons are hot.
Well, hotter than they should be, for being so far from the sun.
In a process called tidal heating, gravitational tugs from...
How the Milky Way stole an enormous gas halo from our dwarf neighbors
There is a huge halo of gas circling our Galaxy with the mass of a billion Suns.
Stripped from the two dwarf Magellanic galaxies that...
Carbon-rich exoplanets could be made of diamonds, says study
As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists...
