Arctic sea ice is melting more quickly than once assumed. Today's climate models have yet to incorporate the steep rise in temperatures that have occurred over the past 40 years. This, according to a new study by researchers at...
The dwarf planet Ceres—long believed to be a barren space rock—is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed Monday.
Ceres is the largest object in the asteroid belt between Mars...
Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA's MAVEN spacecraft. The results are being used to illuminate complex circulation patterns in the Martian atmosphere.
The MAVEN team was surprised to find that...
Taking advantage of a total lunar eclipse, astronomers using NASA's Hubble Space Telescope have detected Earth's own brand of sunscreen—ozone—in our atmosphere. This method simulates how astronomers and astrobiology researchers will search for evidence of life beyond Earth by...
An international team of solar physicists, including academics from Northumbria University, in Newcastle upon Tyne, has recently measured the global magnetic field of the outer most layer of the Sun's atmosphere, the solar corona, for the first time.
The team,...
Using the supersharp radio "vision" of the National Science Foundation's continent-wide Very Long Baseline Array (VLBA), astronomers have discovered a Saturn-sized planet closely orbiting a small, cool star 35 light-years from Earth. This is the first discovery of an...
Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA's Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior may explain...
When two neutron stars slam together, the result is sometimes a black hole that swallows all but the gravitational evidence of the collision. However, in a series of simulations, an international team of researchers including a Penn State scientist...
A large number of the valley networks scarring Mars's surface were carved by water melting beneath glacial ice, not by free-flowing rivers as previously thought, according to new UBC research published today in Nature Geoscience. The findings effectively throw cold...
New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low 1.6% oxygen abundance, breaking the previous record of the lowest abundance. The measured...
Earth. A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter.
This is the conclusion of a study led by UC Riverside astrobiologist Stephen Kane published this...
