10 New Planets in Stars' Habitable Zones
In the most recent catalog of exoplanets discovered by the Kepler mission, ten planets were rocky planets comparible in size to Earth and orbiting within their star's habitable zones--a distance where surface temperatures are warm enough to support liquid water.
Hubble Finds Dead Galaxy
Astronomers have found the first example of a massive, fast-spinning disk-shaped galaxy that stopped making stars only a few billion years after the big bang. This surprising discovery challenges the current understanding of how massive galaxies form and evolve.
Mission Finds Escaping Stars
The European Space Agency's Gaia spacecraft has found six new hypervelocity stars; one is moving so fast that it may eventually leave our Milky Way galaxy.
Early Mars May Have Migrated
A new model simulating the assembly of the solar system around 4.56 billion years ago, suggests that the Red Planet didn’t form in the inner solar system alongside the other terrestrial planets as previously thought. Mars instead may have formed around where the asteroid belt is now and migrated inward to its present-day orbit.
Milky Way in Cosmic Void
If the Milky Way exists in the biggest cosmic void ever observed, that could solve a puzzling mismatch between ways to measure how fast the universe is expanding. Astronomers have found that our galaxy has far fewer galactic neighbors than it should. Research shows a rise in density about 1 billion light-years out, suggesting the Milky Way resides in an abyss about 2 billion light-years wide.
NASA Spacecraft Spots Jupiter's Great Red Spot
Scientists have been wondering about the origin and nature of Jupiter's Great Red Spot for hundreds of years. On July 10, the Juno missiontook the best images of this massive storm.
Delaware-sized Iceberg Breaks Free from Antarctica
An iceberg roughly the size of Delaware has broken off Antarctica’s Larsen C ice shelf. Anticipated for weeks, the fracture is one of the largest calving events ever recorded. Scientists had been monitoring Larsen C since 2014, when they noticed that a crack in the ice shelf had grown roughly 20 kilometers in less than nine months. The ice loss dramatically alters the landscape of Larsen C, and may be a precursor to something much bigger, potentially the collapse of the whole Larsen C ice shelf.
