Scientists ancient lakebed deep beneath Greenland ice
2020/11/20
Scientists have detected what they say are the sediments of a huge ancient lakebed sealed more than a mile beneath the ice of northwest Greenland -- the first-ever discovery of such a sub-glacial feat...
Since the mid-1990s, when the first planet around another sun-like star was discovered, astronomers have been amassing what is now a large collection of exoplanets—nearly 3,500 have been confirmed so ...
The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the Sun, according to a new study led by a scientist at the National Cente...
If you thought Luke Skywalker's home planet, Tatooine, was a strange world with its two suns in the sky, imagine this: a planet where you'd either experience constant daylight or enjoy triple sunrises...
That is just what happens in an unnamed binary star system nearly 10,000 light years from Earth. The newly discovered system, known only by its astronomical catalog number TYC 2505-672-1, sets a new r...
Washington, D.C.--A two-person team of Carnegie's Scott Sheppard and Chadwick Trujillo of the Gemini Observatory has discovered a new active asteroid, called 62412, in the Solar System's main asteroid...

Top and side views of the Milky Way galaxy show the location of four of the new class of hypervelocity stars. These are sun-like stars that are moving at speeds of more than a million miles per hour r...
Lemaître and Hubble: What was discovered - if any - in 1927-29??
Lemaî tre Hubble discovered
2011/10/20
The Big Bang predicted theoretically by Friedmann could not be discovered in the 1920th, since global cosmological distances (more than 300-1000 Mpc) were not available for observations at that time. ...
