NASA has added a further 12 images to its already stunning Hubble gallery of Messier deep-sky objects. The updated collection highlights the power of the Hubble Space Telescope, and its ability to provide spectacularly detailed, views of remote cosmic objects.

According to a newly published paper, the distant halo of stars that orbits the Milky Way could include parts of our own galaxy that were forcefully ejected following a dramatic collision or close pass with a smaller dwarf galaxy.

Black holes can be anywhere from a few times the mass of the Sun up to millions of times that, but some even bigger than that. A new study of data gathered by NASA’s Chandra X-ray telescope has found these so-called “ultramassive” black holes may be larger and more common than we thought.

The Hubble Space Telescope has captured a stunningly detailed view of the weakly barred spiral galaxy NGC 3344, which is located some 20 million light-years away in the direction of the "Lion Cub" constellation, Leo Minor.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) observatory in Chile have imaged a very active black hole at the center of spiral galaxy M77, which is apparently feasting on the universe’s largest donut.

As of January 2018, well over 3,500 exoplanets have been confirmed in the Milky Way, and it was basically a given that planets were pretty common across the universe. Now astrophysicists from the University of Oklahoma (OU) have confirmed the first detection of extragalactic exoplanets.

The first intriguing findings have been released from the Dark Energy Survey, a project studying the mysterious force that seems to be accelerating the expansion of the universe. The study has discovered 11 new stellar streams, the remains of other galaxies that our own Milky Way has torn to shreds.

In 2017 we witnessed a solar eclipse cross the US, welcomed an interstellar visitor, and discovered some exciting Earth-sized exoplanets. Some astonishing images of the farthest reaches of our universe were also captured. Here we collect some of the most awe-inspiring space images of 2017.

With intense gravity and radiation, the region around the supermassive black hole at the center of the galaxy was thought to be too harsh for star formation. But now almost a dozen young rebellious stars have been spotted there anyway, triggering a rethink of our understanding of how stars are born.
