Spiral Galaxy

Astronomers have discovered the oldest known spiral galaxy. It's thought be similar to what our own Milky Way galaxy looked like, 1 billion years after the Big Bang. The post Astronomers spy the oldest known spiral galaxy first appeared on EarthSky.

NASA's Hubble Space Telescope takes an updated look at the Sombrero Galaxy (Messier 104), with new data and image processing techniques.

The James Webb Space Telescope has discovered Zhúlóng, a candidate for the most distant spiral galaxy in the universe. The perplexing Milky Way 'twin' dates to 1 billion years after the Big Bang, and appears too big to explain.

Nicknamed the "Big Wheel," a giant, spiral-shaped disk galaxy was spotted in an unusually crowded part of the early universe just two billion years after the big bang

This Hubble image features the spiral galaxy NGC 4941, located about 67 million light-years away in the constellation Virgo.

2MASX J23453268-0449256 (J2345-0449 for short) harbors a supermassive black hole billions of times the Sun's mass which is powering colossal radio jets stretching 6 million light-years across.

Scientists have discovered a star-smothering black hole energy jet tearing through a galaxy similar to the Milky Way.

Astronomers have spotted a cosmic anomaly: a huge, delicate spiral galaxy with massively powerful jets. What does this mean for our Milky Way galaxy? The post Cosmic anomaly hints at frightening future for Milky Way first appeared on EarthSky.

The Euclid space telescope has spotted 26 million galaxies in just one week of observations.

After finding the debris of two colliding stars swimming in the ocean, researchers are after more evidence from the lunar soil.

In the 1840s, the Leviathan of Parsonstown, built by William Parsons, third Earl of Rosse, became the largest telescope in the world.

The Hubble Space Telescope has captured a new bird's-eye view and 3D map of the Andromeda galaxy and its ecosystem of 36 dwarf satellite galaxies. The post New map of Andromeda galaxy and its colossal ecosystem first appeared on EarthSky.

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows how this theory of gravitational memory could finally be proven.

Astronomers using the NASA/ESA Hubble Space Telescope have produced a beautiful new image of the intermediate spiral galaxy NGC 5042.

The star that exploded to create this cosmic wonder was about 20 times bigger than our sun.

We look back on about 11 years of the Gaia spacecraft, now at the end of its mission to create the best map of the Milky Way.

A shell of icy objects at the edge of the solar system known as the Oort cloud has a pair of spiral arms that resemble a miniature galaxy, new research suggests.

Pluto was discovered 95 years ago. It has captured imaginations ever since.

Researchers believe they have rediscovered a mysterious star system first spotted in 2011. If true, the alien sun and its exoplanet companion are speeding through our galaxy at more than 1.2 million mph. However, it is unclear if this is really the case.

A supernova and its host galaxy are the subject of this NASA/ESA Hubble Space Telescope image. The galaxy in question is LEDA 132905 in the constellation
