International researchers have, for the first time, pinpointed the moment when planets began to form around a star beyond the Sun. Using the ALMA telescope, in which the European Southern Observatory (ESO) is a partner, and the James Webb Space Telescope, they have observed the creation of the first specks of planet-forming material — hot minerals just beginning to solidify. This finding marks the first time a planetary system has been identified at such an early stage in its formation and opens a window to the past of our own Solar System.
New Haven, Conn. — Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the “Infinity” galaxy — two recently-collided galaxies that, together, look like the symbol for infinity.
And at the center of “Infinity,” embedded in a cloud of gas, they say, is a supermassive black hole.
The findings are described in a new study to be published in The Astrophysical Journal Letters.
