Detecting cosmic rays from a galaxy far, far away

Science Daily Astronomy - 8 hours 27 min ago
Where do cosmic rays come from? Solving a 50-year-old mystery, a collaboration of researchers has discovered it's much farther than the Milky Way.

Solar eruption ‘photobombed’ Mars encounter with Comet Siding Spring

Science Daily Astronomy - 12 hours 50 min ago
When Comet C/2013 A1 (Siding Spring) passed just 140,000 kilometers from Mars on 19th October 2014, depositing a large amount of debris in the Martian atmosphere, space agencies coordinated multiple spacecraft to witness the largest meteor shower in recorded history. It was a rare opportunity, as this kind of planetary event occurs only once every 100,000 years.

Unique type of object discovered in our solar system

Science Daily Astronomy - Wed, 2017-09-20 14:47
Astronomers have observed the intriguing characteristics of an unusual type of object in the asteroid belt between Mars and Jupiter: two asteroids orbiting each other and exhibiting comet-like features, including a bright coma and a long tail. This is the first known binary asteroid also classified as a comet.

New concept of terrestrial planet formation

Science Daily Astronomy - Wed, 2017-09-20 13:17
Scientists are proposing a new way of understanding the cooling and transfer of heat from terrestrial planetary interiors and how that affects the generation of the volcanic terrains that dominate the rocky planets.

Is the Milky Way an 'outlier' galaxy? Studying its 'siblings' for clues

Science Daily Astronomy - Wed, 2017-09-20 11:33
The most-studied galaxy in the universe -- the Milky Way -- might not be as 'typical' as previously thought, according to a new study. Early results from the Satellites Around Galactic Analogs (SAGA) Survey indicate that the Milky Way's satellites are much more tranquil than other systems of comparable luminosity and environment. Many satellites of those 'sibling' galaxies are actively pumping out new stars, but the Milky Way's satellites are mostly inert.

Mercury's poles may be icier than scientists thought

Science Daily Astronomy - Tue, 2017-09-19 12:31
A new study identifies three large surface ice deposits near Mercury's north pole, and suggests there could be many additional small-scale deposits that would dramatically increase the planet's surface ice inventory.

Size matters in the detection of exoplanet atmospheres

Science Daily Astronomy - Tue, 2017-09-19 09:26
A group-analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planet’s atmosphere can be detected. The largest population-study of exoplanets to date successfully detected atmospheres around 16 ‘hot Jupiters’, and found that water vapor was present in every case.

Solar wind impacts on giant 'space hurricanes' may affect satellite safety

Science Daily Astronomy - Tue, 2017-09-19 09:10
Could the flapping of a butterfly's wings in Costa Rica set off a hurricane in California? For most people, this hypothetical scenario may be difficult to imagine on Earth -- particularly when a real disaster strikes. Yet, in space, similarly small fluctuations in the solar wind as it streams toward the Earth's magnetic shield actually can affect the speed and strength of 'space hurricanes,' a researcher explains.

Supermassive black holes found in the centers of galaxies can form gravitationally bound pairs when galaxies merge, according to a new study.

Secrets of bright, rapidly spinning star revealed

NASA's Cassini spacecraft ends its historic exploration of Saturn

Science Daily Astronomy - Sat, 2017-09-16 10:30
A thrilling epoch in the exploration of our solar system has come to a close, as NASA's Cassini spacecraft made a fateful plunge into the atmosphere of Saturn, ending its 13-year tour of the ringed planet. Cassini's plunge brings to a close a series of 22 dives between Saturn and its rings, a feat never before attempted by any spacecraft.
