The explosion that formed DEM L316A was an example of an especially energetic and bright variety of supernova, known as a Type Ia. Such supernova events are thought to occur when a white dwarf star steals more material than it can handle from a nearby companion, and becomes unbalanced.

All seven of the exoplanets — currently referred to by the letters 'b' through 'h' — could have liquid water, and three of the planets — 'e', 'f', and 'g' — are orbiting within the right range of distances from the dwarf star to potentially allow oceans to form on the planet's surface.

According to a team of astronomers whose research will be published in a forthcoming issue of Monthly Notices of the Royal Astronomical Society, there's also a chance that the Cow event was a massive black hole ripping apart a white dwarf star—an astronomical event known as a tidal disruption.

Plasma is usually produced in extremely high temperature environments, such as the surface of the Sun, but in even more extreme environments (like at the center of an ultra-dense white dwarf star or Jupiter) plasma begins to behave in unusual ways that are difficult to replicate in a lab on Earth.

Swirling around a red-dwarf star about 183 light-years away from Earth, the distant world sits in a so-called Goldilocks zone—not close enough to its host star to be too hot and not far enough away to be too cold—that could allow liquid water to flow across its surface.

In March 2000, researchers using a specialized instrument called the Ultraviolet and Visual Echelle Spectrograph at the European Southern Observatory (ESO) in Chile picked up the first hints that Proxima Centauri was being dragged radially at a velocity of about one meter per second, perhaps by a small planet orbiting the red dwarf star.

Image: System SoundsIf you, like me, are an overly sweaty nerd with no musical ability who has always dreamed of being a less sweaty nerd with some musical ability, now's your chance: a team of astronomers and musicians have created a program that allows you make songs with the sounds of planets orbiting the ultracool dwarf star TRAPPIST-1.

For three days in October, organizers of the Spanish Sónar electronic music festival pointed the 23-foot-wide European Incoherent Scatter Scientific Association (EISCAT) radio antenna towards the sky and sent bursts of radio signals towards GJ 210—a red dwarf star (sometimes called Luyten's Star) that hosts two known planets, one of which, GJ 216b, may be capable of supporting life.

The fun starts at 8 PM ET/5 PM PT. Proxima Centauri is a small red dwarf star located just 4.25 light years away, slightly closer to Earth than the famous binary pair of Alpha Centauri A and B. The newly discovered exoplanet has been dubbed Proxima b, and the ESO team pegs its mass as being roughly 1.3 times that of Earth.

This part of Einstein's prediction is called 'astrometric lensing' and Sahu's team was the first to observe it in a star other than the sun … Sahu's team measured shifts in the apparent position of a distant star as its light was deflected around a nearby white dwarf star called Stein 2051 B on eight dates between October 2013 and October 2015.

One caps-heavy passage declares: THE WORK OF A PECULIAR AND ECCENTRIC NUT CAN TRULY BE CALLED "NUT ART" … THE NUT ARTIFICER TRAVELS IN A PHANTASMAGORIC MICRO-WORLD, SMALL AND EXTREMELY COMPACT, AS IS THE LIGHT OF A DWARF STAR IMPLODING INWARD AND IN PASSAGE COLLAPSING PARADISE AND HELL TO ONE AS IT VANISHES FOREVER WITH OUR JOYS, SORROWS AND UNREQUITED LOVE.

Scientists have subsequently theorized that they're the glowing remnant of a gamma-ray burst (a massive explosion produced by a collapsing star that gives birth to a black hole), a supernova fueled by a magnetar (a neutron star with a powerful magnetic field), or a failed Type Ia supernova (in which a white dwarf star sucks up material from a nearby star, eventually causing it to explode).

Proxima Centauri is a small red dwarf star located just 4.25 light years away, slightly closer to Earth than the famous binary pair of Alpha Centauri A and B. (It is actually believed to be gravitationally bound to Alpha Centauri, making the system a trinary.) Smaller and fainter than our sun, red dwarfs comprise roughly 80 percent of all stars in the Milky Way, although we don't see them when we look up into the sky at night.

A Star Came Within 0.8 Light-Years Of Our Sun 70,000 Years AgoAn international team of astronomers has identified a star that passed through the outer reaches of …Read more ReadAccording to this research, a dim red dwarf star, along with its even dimmer brown dwarf companion—a kind of bloated gas giant that failed to ignite into a full-blown star—came to within 0.8 light-years of our Sun (4.7 trillion miles, or 0003,600 AU, where 1 AU is the average distance of the Earth to the Sun), and possibly as close as 0.6 light-years (236 trillion miles, or 22015,214 AU).
