The Colliding Spiral Galaxies of Arp 271
21.07.2008

What will become of these galaxies? Spiral galaxies NGC 5426 and NGC 5427 are passing dangerously close to each other, but each is likely to survive this collision. Most frequently when galaxies collide, a large galaxy eats a much smaller galaxy.

Spiral Galaxy NGC 4038 in Collision
23.05.2018

This galaxy is having a bad millennium. In fact, the past 100 million years haven't been so good, and probably the next billion or so will be quite tumultuous. Visible toward the lower...

Barred Spiral Galaxy NGC 1365 from Webb
18.02.2023

A mere 56 million light-years distant toward the southern constellation Fornax, NGC 1365 is an enormous barred spiral galaxy about 200,000 light-years in diameter. That's twice the size of our own barred spiral Milky Way.

APOD: 2024 February 6 Б NGC 1566: A Spiral Galaxy from Webb and Hubble
6.02.2024

What's different about this galaxy? Very little, which makes the Spanish Dancer galaxy, NGC 1566, one of the most typical and photogenic spirals on the sky. There is something different about this galaxy...

APOD: 2023 May 22 Б Supernova Discovered in Nearby Spiral Galaxy M101
22.05.2023

A nearby star has exploded and humanity's telescopes are turning to monitor it. The supernova, dubbed SN 2023ifx, was discovered by Japanese astronomer Koichi Itagaki three days ago and subsequently located on automated images from the Zwicky Transient Facility two days earlier.

Arp 240: A Bridge between Spiral Galaxies from Hubble
28.11.2016

Why is there a bridge between these two spiral galaxies? Made of gas and stars, the bridge provides strong evidence that these two immense star systems have passed close to each other and experienced violent tides induced by mutual gravity.

APOD: 2023 October 11 Б NGC 1097: Spiral Galaxy with Supernova
11.10.2023

What's happening in the lower arm of this spiral galaxy? A supernova. Last month, supernova SN 2023rve was discovered with UAE's Al-Khatim Observatory and later found to be consistent with the death explosion of a massive star, possibly leaving behind a black hole.

The Supernova and Cepheids of Spiral Galaxy UGC 9391
6.06.2016

What can this galaxy tell us about the expansion rate of the universe? Perhaps a lot because UGC 9391, featured, not only contains Cepheid variable stars (red circles) but also a recent Type Ia supernova (blue X).
