Researchers Model Source of Eruption on Jupiter’s Moon Europa
On Jupiter’s icy moon Europa, powerful eruptions may spew into space, raising questions among hopeful astrobiologists on Earth: What would blast out from miles-high plumes? Could they contain signs of extraterrestrial life? And where in...
The Universe Is Getting Hot, Hot, Hot, a New Study Suggests
The universe is getting hotter, a new study has found. The study, published in the Astrophysical Journal, probed the thermal history of the universe over the last 10 billion years. It found that the mean temperature of...

Tree Rings May Hold Clues to Impacts of Distant Supernovas on Earth
Massive explosions of energy happening thousands of light-years from Earth may have left traces in our planet’s biology and geology, such as tree rings, according to new research by CU Boulder geoscientist Robert Brakenridge.  The...

Escape from Mars: How water fled the red planet
Mars once had oceans but is now bone-dry, leaving many to wonder how the water was lost. University of Arizona researchers have discovered a surprisingly large amount of water in the upper atmosphere of Mars,...

NASA Contacts Voyager 2 Using Upgraded Deep Space Network Dish
On Oct. 29, mission operators sent a series of commands to NASA's Voyager 2 spacecraft for the first time since mid-March. The spacecraft has been flying solo while the 70-meter-wide (230-foot-wide) radio antenna used to talk to...
Intense Radio Burst in Milky Way Could Help Resolve Origins of Mysterious Phenomenon
New data from a Canadian-led team of astronomers, including researchers from the McGill Space Institute and McGill University Department of Physics, strongly suggest that magnetars — a type of neutron star believed to have an extremely powerful magnetic...

An Earth-Sized Rogue Planet Discovered in the Milky Way
Our Galaxy may be teeming with rogue planets, gravitationally unbound to any star. An international team of scientists, led by Polish astronomers from the University of Warsaw, has announced the discovery of the smallest Earth-sized...

Mars Plays Shepherd to Our Moon’s Long-Lost Twin
An international team of planetary scientists, led by astronomers at AOP, have found an asteroid trailing behind Mars with a composition very similar to the Moon’s. The asteroid could be an ancient piece of debris,...
How Many Habitable Planets Are Out There?
Thanks to new research using data from the Kepler space telescope, it’s estimated that there could be as many as 300 million potentially habitable planets in our galaxy. Some could even be pretty close, with...
