Deep within the Andromeda constellation, some 320 million light-years away, two galaxies are consumed by a gravitationally bound dance, and the Hubble Space Telescope has just photographed the action in extraordinary three-dimensional detail. The two dancers are the smaller polar-ring galaxy IC 1559 (top) and the larger spiral galaxy NGC 169 (bottom). Collectively, they are … Read more
A new Hubble image shows two deceivingly close galaxies located in the constellation Virgo. The Hubble Space Telescope captured the barred spiral galaxy NGC 4496A and the spiral galaxy NGC 4496B. The two galaxies only appear to overlap due to a chance alignment — in reality, they are actually located incredibly far apart. NGC 4496A … Read more
Millions of new objects have just been cataloged in a vast new sky map that will lead to more investigations about our universe’s environment, the discovery team says. A map of roughly one-quarter of the northern sky was generated using a pan-European set of telescopes called the Low Frequency Array (LOFAR). It detected objects that … Read more
It’s been nearly 350 years since Sir Issac Newton wrote, “If I have seen further it is by standing on the shoulders of giants,” but the sentiment certainly holds true today. Newton’s wisdom is exemplified by a grand project called the Cosmic Evolution Survey, or COSMOS. COSMOS builds on the legacy of the Hubble Space … Read more
The Hubble Space Telescope continues to scout on behalf of the newly launched James Webb Space Telescope to guide future astronomy work. A stunning new image released by Hubble officials shows a single example of that collaboration: a pair of galaxies known as Arp 298, interacting 200 million light-years from Earth in the constellation Pegasus. … Read more
A billion years ago, an absolutely monstrous collision of two clusters of galaxies produced a pair of shock waves of absolutely epic proportions. Today, the structures gleam brightly in radio wavelengths, so huge they could easily engulf the Milky Way galaxy’s estimated 100,000 light-year diameter, stretching up to 6.5 million light-years through intergalactic space. … Read more
An object 681 million light-years away might look like one glorious, exquisite mess, but there’s a lot more going on that a first glance indicates. The object showcased in a new Hubble image – called IC 2431 – is not one galaxy, but three, coming together in a massive galactic merger that will one day … Read more
Three galaxies collide in this stunning new Hubble Space Telescope image showing the galaxy cluster IC 2431 about 681 million light-years from Earth. (Image credit: ESA/Hubble & NASA, W.

Over the course of the history of the Universe, the Milky Way has not been serenely sailing through intergalactic space. Quite the contrary, actually. Over the last 13.6 billion years or so, it has collided with and consumed multiple other galaxies. Now, through painstaking work, astronomers led by Khyati Malhan of the Max Planck … Read more
The ongoing interaction between two galaxies 320 million light-years away has been captured in a gorgeous Hubble image. They’re collectively known as Arp 282 in Halton Arp’s Atlas of Peculiar Galaxies, and they consist of a large barred spiral galaxy named NGC 169, about 140,000 light-years across, and a much smaller polar-ring galaxy named IC … Read more
