Young planetary systems generally experience extreme growing pains, as infant bodies collide and fuse to form progressively larger planets. In our own solar system, the Earth and moon are thought to be products of this type of giant impact. Astronomers surmise that such smashups should be commonplace in early systems, but they have been difficult to observe around other stars.

The Gaia spacecraft was launched in 2013 by the European Space Agency. According to NASA, “Its goal is to create the largest, most precise three-dimensional map of the Milky Way by surveying about 1% of the galaxy's 100 billion stars.” Photometry and spectroscopy are also possible for many of the observed objects. The observation mode is based on continuous scanning by two telescopes simultaneously with a 64-day precession movement around the Sun. This scanning mode allows Gaia to map the entire sky in several months and also makes it impossible to follow-up a specific target when necessary.

In the early solar system, a “protoplanetary disk” of dust and gas rotated around the sun and eventually coalesced into the planets we know today. A new analysis of ancient meteorites by scientists at MIT and elsewhere suggests that a mysterious gap existed within this disk around 4.567 billion years ago, near the location where the asteroid belt resides today.

NGC 4666 takes center stage in this image from the NASA/ESA Hubble Space Telescope. This majestic spiral galaxy lies about 80 million light-years away in the constellation Virgo and is undergoing a particularly intense episode of star formation. Astronomers refer to galaxies that rapidly form stars as starburst galaxies. NGC 4666’s starburst is likely due to gravitational interactions with its unruly neighbors – including the nearby galaxy NGC 4668 and a dwarf galaxy, which is a small galaxy made up of a few billion stars.

Recently, astronomers have been finding protoplanetary discs around certain stars. Their discovery has helped kick off a new work in planetary formation theory. But planets aren’t the objects that form from discs of material in space. Moons do too. Now, scientists led by Dr. Tomas Stolker of Leiden University and his team have delved deeper into the characteristics of a “protolunar” disc surrounding a “super Jupiter” exoplanet about 500 light-years away.

Let's cut right to the chase, shall we? No one knows what causes Fast Radio Bursts, intense but extremely short blasts of radio waves. By "intense" I mean pouring out possibly millions of times the energy the Sun does, and by "short" I mean short: they literally last a millisecond or so. A thousandth of a second.
