Ultra-close stars discovered inside a planetary nebula

An image obtained with the Hubble Space Telescope of the planetary nebula M3-1, the central star of which is actually a binary system with one of the shortest orbital periods known.

An international team of astronomers have discovered two stars in a binary pair that complete an orbit around each other in a little over three hours, residing in the planetary nebula M3-1. Remarkably, the stars could drive a nova explosion, an entirely unexpected event based on our current understanding of

First Bose-Einstein Condensate Created In Space


An international team of physicists reports that they have successfully produced a Bose-Einstein condensate in space for the first time. In the study published this past week in Nature, the group describes how they created a small device capable of producing a Bose-Einstein condensate, attached it to a rocket, and the

NASA Discovered A Solar System With 7 Earth-Like Planets


Scientists working with telescopes at the European Southern Observatory and NASA announced a remarkable new discovery: An entire system of Earth-sized planets. If that’s not enough, the team asserts that the density measurements of the planets indicates that the six innermost are Earth-like rocky worlds. And that’s just the beginning. Three of

NASA Voyager 2 could be nearing interstellar space

This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere.

NASA's Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system. Launched in 1977, Voyager 2 is a little less than 11 billion miles (about 17.7 billion kilometers) from Earth, or more than 118 times the distance

Black Holes Ruled Out As Universe’s Missing Dark Matter

A supernova (bright spot at lower left) and its host galaxy (upper center), as they would appear if gravitationally lensed by an intervening black hole (center).

For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe’s mysterious dark matter might consist of a plenitude of black holes sprinkled throughout the universe. UC Berkeley physicists have dashed those hopes. Based on a statistical analysis of

Hubble Takes Spectacular Photo of Vast Galaxy Cluster

Hubble Space Telescope

The Hubble Space Telescope has captured a spectacular image showing a vast collection of galaxies located around 4 billion light-years from Earth. The cluster, known as Abell 370—located in the constellation Cetus—is the first target of a new Hubble mission known as the BUFFALO survey, which aims to broaden our understanding of
