This new Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627. This cluster is violently ripping the spiral's entrails out into space, leaving bright blue streaks as telltale clues to this cosmic crime.
A giant sunspot - a magnetically strong and complex region on the sun's surface - has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation.
A team of Australian and American astronomers have been studying nearby galaxy M83 and have found a new superpowered small black hole, named MQ1, the first object of its kind to be studied in this much detail.
The closest and brightest supernova in decades, SN 2014J, brightens faster than expected for Type Ia supernovae, the exploding stars used to measure cosmic distances, according to University of California Berkeley astronomers.
Stowed inside ESA's next supply ship to the International Space Station will be one of the most advanced joysticks ever built, designed to test the remote control of robots on the ground from up in orbit.
New images from the Smithsonian's Submillimeter Array (SMA) telescope provide the most detailed view yet of stellar nurseries within the Snake nebula. These images offer new insights into how cosmic seeds can grow into massive stars.
A team of scientists have looked at how these worlds form and suggest that many of them may be a lot less clement than was though. They find that planets that form from less massive cores can become benign habitats for life, whereas the larger objects instead end up as 'mini-Neptunes' with thick atmospheres and probably stay sterile.
A physicist at Heidelberg University has developed a theoretical model that complements the nearly 100-year-old conventional model of cosmic expansion. According tohis theory, the Big Bang did not occur 13.8 billion years ago - instead, the birth of the universe stretches into the infinite past.
This is the first time that astronomers have reported a clear detection of a relatively rare nitrogen isotope in a single comet and also measured the relative abundance of two different forms of nitrogen of cometary ammonia.
A meteorite with the mass of a small car crashed into the Moon last September, according to Spanish astronomers. The impact, the biggest seen to date, produced a bright flash and would have been easy to spot from the Earth.
The Andromeda Galaxy is surrounded by a swarm of small satellite galaxies. Researchers from the Niels Bohr Institute, among others, have detected a stream of stars in one of the Andromeda Galaxy's outer satellite galaxies, a dwarf galaxy called Andromeda II. The movement of the stars tells us that what we are observing is the remnant of a merger between two dwarf galaxies. Mergers between galaxies of such low mass has not been observed before.
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a day.
