Best Astronomy Photography of the Year 2020

Images of the Milky Way, California nebula and Andromeda galaxy are among the winners of the Insight Investment astronomy photographer of the year award. 

Hubble maps giant halo around Andromeda Galaxy

Scientists were surprised to find that this tenuous, nearly invisible halo of diffuse plasma extends 1.3 million light-years from the Andromeda galaxy and as far as 2 million light-years in some directions.

Universe Could Be 12.6 Billion Years Old

Using known distances of 50 galaxies from Earth to refine calculations in Hubble's constant, astronomers estimates the age of the universe at 12.6 billion years, different to the value of 13,8 billion years.

X-Galaxy Powered by a Monster Black Hole

The prominent X-shape of PKS 2014-55 is made up of two pairs of giant lobes consisting of hot jets of electrons. These jets spurt outwards from a supermassive black hole at the galaxy's heart.

Study examines which galaxies are best for intelligent life

Giant elliptical galaxies are not as likely as disk-shaped galaxies, such as our own Milky Way, to be cradles of technological civilizations, according to a recent U.S. paper.

How the universe got its structure

The universe is full of billions of galaxies. Why do we see so much structure in the universe today? A 10-year survey of tens of thousands of galaxies has provided a new approach to answering this fundamental mystery.

Hubble at 30: A cosmic legacy

30 years ago the Hubble Space Telescope blasted off the launch pad aboard the space shuttle Discovery, ushering in a new era for astronomy that has transformed our understanding of the Universe around us.

Milky Way May Have 100 Faint Satellite Galaxies

A new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.

Hubble Telescope Detects Unthinkable Quasar Tsunamis

Scientists using the Hubble Space Telescope have detected quasars sending outbursts of energy roaring through their galaxies, according to new research.

"Godzilla" galaxy hosts a trillion suns

The largest spiral galaxy in the local universe UGC 2885, is 2.5 times wider than the Milky way and hosts a trillion stars, 10 times more than Earth’s galactic home. UGC 2885 is located some 232 million light years away in the constellation Perseus.

A Galaxy That Formed Less than a Billion Years After the BB

Astronomers have spotted an unusually distant star-forming galaxy, the light of which took a whopping 13 billion years to reach Earth. Perhaps most incredibly, however, the galaxy was observed directly, without gravitational lensing.

Three supermassive black holes in galactic merging

Extensive observations indicated the presence of three supermassive back holes in the three galaxies NGC 6240 that are  the process of merging. Up until now, such a concentration of supermassive black holes had never been discovered in the universe.

Something is syncing the movements of galaxies

Scientists have been gathering a growing well of evidence that our universe may be connected via a vast array of large-scale "structures" that seem to reach out across the cosmos to synchronize the movements of galaxies that are separated by vast distances.

Chandra spots a mega-cluster of galaxies in the making

The new observations show a mega-structure being assembled in a system called Abell 1758, located about three billion light-years from Earth. It contains two pairs of colliding galaxy clusters that are heading toward one another.

Giant radio galaxies defies conventional wisdom

When we look far into the distant universe - we expect to find distant giant radio galaxies comparatively small. But to our surprise the new research found that these giants still appear enormous even though they are so far away.
