The Magellanic Clouds — two nearby dwarf galaxies easily visible to the naked eye in the southern hemisphere — are key to understanding the dynamics and evolution of the Local Group of galaxies. Can an in-depth look at these galaxies’ outer regions help us make sense of their complicated interaction history?
Astronomers have discovered a pulsar that comes with its own magnifying glass — courtesy of its brown dwarf companion that’s being torn to shreds.
An intriguing asteroid was spotted traveling backwards around Jupiter back in 2015. Now a team of researchers think it could have formed around another star.
A Dutch radio astronomy experiment hitched a ride today with China's relay satellite for the upcoming Chang'e 4 mission.
The Cygnus OA-9 mission launching from Wallops Island early Sunday morning could put on quite a show along the East Coast.
New observations suggest that stars were forming just 250 million years after the Big Bang — a record-breaker that will likely open a new line of cosmological inquiry.
A small helicopter will be the first mission to fly through the skies of Mars.
A new analysis of decades-old data from NASA’s Galileo spacecraft, which reached the Jupiter system in 1995, shows the best evidence yet for plumes from the icy moon Europa.
This week in astronomy news: Researchers discover the first completely cloud-free exoplanet and a star-forming cloud reveals its structure through vibrations.
The RXTE satellite, which reentered Earth's atmosphere over the tropics on April 30th, leaves behind a legacy of discoveries and data.
The gravitational-wave detection last year of a neutron star merger has revealed details on neutron star structure, ruling out exotic quark matter in the objects’ cores.
Jupiter's at opposition this week. Close and bright, it shines like a midnight version of Venus. No matter your scope, the biggest planet is always a crowd-pleaser.
The Mars Cube One mission — the first to send CubeSats into interplanetary space — will test revolutionary relay technologies as it accompanies Mars Insight to the Red Planet.
Rising through thick fog from Vandenberg Air Force Base in California. NASA's latest mission intends to probe deeply into Mars and decipher how it formed.
Stephen Hawking’s last paper on cosmology, published posthumously, might solve the problem of eternal inflation, a theory that suggests our cosmos is but one in a sea of infinite universes.
New simulation work suggests that galaxies like the Milky Way could be home to a dozen supermassive black holes.
Hubble observations reveal a Jupiter-size exoplanet losing its atmosphere in a system 200 light-years away.
In a rare move, a sleepy cataclysmic variable blows its top and suddenly becomes a nova.
This month's astronomy podcast tells you how to use Venus and the Big Dipper to find many bright stars and constellations. Meanwhile, Jupiter lurks low in the east after darkness falls.
A short take on astronomy news finds a cosmic butterfly testing theories of galactic evolution, a new idea for the formation of Mars's moons, and the discovery of a stellar thief that survived a supernova explosion.
At least 14 galaxies are swarming in the early universe, forming a protocluster with the mass of 10 trillion Suns. It might become one of the most massive structures in the universe.
With its second data release, the European Space Agency's Gaia satellite has redefined the way we look at our galaxy.
Curiosity spotted polygonal shapes on the surface of rocks on Mars — now, analysis of these mud cracks is revealing the history of the long-ago lake that once filled Gale Crater.
To celebrate Hubble's 28th birthday NASA is releasing a brand-new image of the Lagoon Nebula, a vast stellar nursery.
The editors of Sky & Telescope report experiences from last weekend's Northeast Astronomy Forum (NEAF) in Suffern, New York — one of the busiest years ever for the world's biggest astronomy trade show.
