A NASA telescope that will give humans the largest, deepest, clearest picture of the universe since the Hubble Space Telescope could find as many as 1,400 new planets outside Earth’s solar system, new research suggests.

NASA has selected a new space mission that will help astronomers understand both how our universe evolved and how common are the ingredients for life in our galaxy’s planetary systems.

Astronomers say they have the first evidence of a head-on collision between two planets in a distant star system.
They believe two objects smacked into each other to produce an iron-rich world, with nearly 10 times the mass of Earth.

A team of astronomers has produced a 3D map of our galaxy, the 1st accurate one, they say. It reveals our galaxy’s true shape as warped and twisted.
We think of spiral galaxies as being flat. You often hear the disk of our galaxy described as “flat as a pancake.” The large spiral galaxy next door – the Andromeda galaxy – looks flat through a telescope. But nature can be intricate, and, this week (February 4, 2019), astronomers made a surprising announcement. They said our home galaxy, the Milky Way, isn’t flat. Instead it’s warped and twisted.

Astronomers using ALMA have detected various complex organic molecules around the young star V883 Ori. A sudden outburst from this star is releasing molecules from the icy compounds in the planet forming disk. The chemical composition of the disk is similar to that of comets in the modern Solar System. Sensitive ALMA observations enable astronomers to reconstruct the evolution of organic molecules from the birth of the Solar System to the objects we see today.

The peculiar movement of gas at the galactic center could be the smoking gun that finally leads astronomers to the most elusive type of black hole – the middleweight.

For only the second time, astronomers have picked up a mysterious repeating signal coming from an unknown source in space.
They’re called fast radio bursts. And in less than the blink of an eye, they ping into the data collected by radio telescopes out of nowhere, with as much energy as a hundred million Suns.

Stars are thought to form inside giant molecular clouds of gas, sometimes with diameters hundreds of light years across, with a combined mass equivalent to millions of solar masses. As these clouds collapse, they form fragments. Said fragments are thought to contain the mass that will become both the star and its protoplanetary disc, though there are opportunities for interactions with other nearby clouds. If an aged star near a stellar nursery goes supernova, for example, heavier elements created by the core collapse may form part of the new stars. A nearby supernova can even trigger the formation of new stars when its shock wave sharply compresses the molecular gas cloud.

Planetologists have obtained detailed photos of the areas in space in which, from a hypothetical point of view, the mysterious ninth rogue planet of the solar system is located.
According to US astronomer Michael Brown, the photographs will help to discover the giant planet.

It was hiding behind the Milky Way.
Through the thick fog of our own galaxy, astronomers have spotted an ultimate prize: one of the largest-known structures in the Universe.
Called the Vela super-cluster, the newly discovered object is a massive group of several galaxy clusters, each one containing hundreds or thousands of galaxies. Continue reading Astronomers have discovered one of the most massive objects in the universe
