Astronomers with the Pale Red Dot Project have announced the discovery of an Earth-like planet orbiting Proxima Centauri, the star closest to Earth. The newfound planet, currently called "Proxima b", has the fortune of being 1.3 times the mass of the Earth, and orbits within the star’s Goldilocks Zone, meaning that it is just the right size and temperature to host liquid water, one of the requirements for life as we know it.

As the old saying goes, life can move pretty fast, but this is especially true in space, where the difference in orbital velocities between two different objects can literally be faster than a speeding bullet. Last month, British astronaut Tim Peake posted a photograph of a 7 mm (1/4 inch) impact chip in one of the International Space Station’s Cupola windows, suspected to have been caused by a miniscule piece of debris no bigger than a few thousandths of a millimeter across.

A team of astronomers have discovered a system of three Earth-like exoplanets orbiting a small star that is only 40 light-years away from Earth, that are considered good candidates for supporting life.

The star in question, an ultracool dwarf called TRAPPIST-1, is only a bit bigger than Jupiter, and only emits approximately one two-hundredths of the output of our Sun, making it too faint to see with the naked eye. The planets in question, however, orbit very close to the star, allowing them to gather enough light from the star to keep warm. Because of their extremely close orbits, the planets orbit TRAPPIST-1 extremely quickly: the innermost planet takes 1.5 Earth days for a single revolution, and the second planet’s year is only 2.4 days.

One of astronomy’s most secretive phenomena, black holes, has yielded yet another fascinating puzzle to astronomers — and in the process, offering what may be new insight into how the universe formed. A recent survey of a region of deep space has found that the powerful jets that are propelled by some supermassive black holes are uncannily aligned, all pointing in the same direction.
