Astronomers discover massive radio galaxy 100 times larger than the Milky Way. Its discovery was "a stroke of luck." A joint radio-infrared view of Alcyoneus, a radio galaxy with a projected proper length of 5.0 megaparsecs.Feb 17, 2022
Has NASA discovered a new galaxy?
NASA recently announced that the observatory might have discovered a new planet in the galaxy known as Messier 51 or M51. The galaxy is popularly known as the “Whirlpool” galaxy. The research recently appeared in the publication Nature Astronomy.
What is the most recent galaxy found?
Astronomers have just found an absolute monster of a galaxy. Lurking some 3 billion light-years away, Alcyoneus is a giant radio galaxy reaching 5 megaparsecs into space. That's 16.3 million light-years long, and constitutes the largest known structure of galactic origin.
When did we discover another galaxy?
1922 — Ernst Öpik distance determination supports Andromeda as extra-galactic object. 1923 — Edwin Hubble resolves the Shapley–Curtis debate by finding Cepheids in the Andromeda Galaxy, definitively proving that there are other galaxies beyond the Milky Way.
Has anything been to another galaxy?
Astronomers spotted what they believe may be the first known planet in another galaxy. More than 4,800 planets have been discovered orbiting stars other than our sun. But until now, all of them have been inside our Milky Way galaxy. The potential new world orbits two stars in the Whirlpool galaxy.
Did scientists find water on Mars?
Subglacial liquid water In July 2018, scientists from the Italian Space Agency reported the detection of such a subglacial lake on Mars, 1.5 kilometres (1 mi) below the southern polar ice cap, and spanning 20 kilometres (10 mi) horizontally, the first evidence for a stable body of liquid water on the planet.
What is past our galaxy?
Beyond our galaxy itself, which holds our solar system and everything beyond it, are other galaxies. The nearest galaxy is Andromeda, which will collide with the Milky Way galaxy in about 4 billion years. The Milky Way is part of the Local Group, which consists of 30 galaxies.
What is a dead galaxy?
The astronomers used one such “lens” to look at “dead” galaxies from when the universe was three billion years old. The “dead” moniker describes the fact that these galaxies no longer have the necessary cold hydrogen gas to make stars.
What is the biggest thing in space?
the Hercules-Corona Borealis Great Wall The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
Who discovered planets?
Brian says that when Galileo put his telescope on Jupiter, he saw four tiny dots moving around the gas giant. “They were all in line with the equator of Jupiter they all moved round… in a regular manner." This showed Galileo something extremely important — that the planets could orbit things other than Earth.
