An experiment in the frozen wastes of Antarctica has revealed evidence of a universe born in the same Big Bang as ours – but with rules of physics that are completely the opposite.
Scientists have detected evidence of a colossal explosion in space – five times bigger than anything observed before.
The huge release of energy is thought to have emanated from a supermassive black hole some 390 million light years from Earth.
The web of stars, known as XMM-2599, existed about 12 billion years ago, in the early days of the universe, when it was only about 1.8 billion years old.
It spewed out a vast number of stars in its short life. And then it suddenly stopped.
Alien life could be discovered in less than two years but the world is ‘not prepared for the results’, NASA’s chief scientist says.
Europe’s ExoMars Rover, which has been named Rosalind in memory of British chemist Rosalind Franklin, will be launched with NASA’s rover Mars 2020 in March.
The supermassive black hole that lives at the center of our galaxy has been mysteriously sparkling as of late, and nobody knows the reason.
This dark behemoth, known as as Sagittarius A* (Sgr A*), is four million times as massive as the Sun. Though no light escapes its boundaries, astronomers can observe the hole’s interactions with bright stars or dust clouds that surround it.
Back in early January, when scientists pulled down their first batch of data from the New Horizons spacecraft, they celebrated an odd snowman-shaped object in the outer Solar System. From this first look, it appeared as though Ultima Thule, formally named 2014 MU69, consisted of two spheres in contact with one another—a contact binary.
Now that scientists have downloaded more data from the distant spacecraft, however, our view of Ultima Thule has changed.
Two newfound galaxies appear to be devoid of the substance, paradoxically providing more proof dark matter exists
Much as a ripple in a pond reveals a thrown stone, the existence of the mysterious stuff known as dark matter is inferred via its wider cosmic influence. Astronomers cannot see it directly, but its gravity sculpts the birth, shape and movement of galaxies. This makes a discovery from last year all the more unexpected: a weirdly diffuse galaxy that seemed to harbor no dark matter at all.
