New Insight Into TRAPPIST 1 Planets
Two new, but separate, studies provide fresh insight into planets orbiting the nearby red dwarf star TRAPPIST-1. One of the studies, published in the journal Nature Astronomy, suggests the atmospheres of at least three of the seven TRAPPIST-1 exoplanets found so far do not seem to be as hydrogen-rich as our solar system’s gas giant […]

A Blast of Gamma Rays from Halfway Across the Universe Detected
Back in April 2015, a surge of high-powered gamma rays from half-way across the universe crashed into Earth’s atmosphere. But, according to the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, the burst of gamma rays didn’t put any of us in danger and produced no noticeable effects since the high-energy rays are blocked by Earth’s atmosphere. Astronomers, using […]
Slumbering Giant Black Hole Awakes After 26 Years
Some 8,000 light years from Earth, in the constellation Cygnus, a binary system known as V404 Cygni has come to life for the first time in 26 years. While most binary systems consist of two stars orbiting a common center of mass, V404 Cygni is made up of a black hole and a star that […]

Ultra-Light Planet Found Outside Solar System
The European Southern Observatory (ESO) has discovered what appears to be the lightest planet ever to be directly observed outside of our Solar System. Astronomers made the discovery using the Very Large Telescope (VLT), located in Chile, which captured the faint object moving near a bright star about 300 light years from Earth. The possible […]
New Imager Finds Distant Planets Unlike Others in Known Universe
Thanks to new technology, astronomers are conducting the first remote reconnaissance of a distant solar system, allowing them to collect the first chemical fingerprints of four exoplanets orbiting a star some 128 light years from Earth. Astronomers involved with Project 1640, a high-contrast imaging program at the Palomar Observatory in California, say the four exoplanets […]
Scientists Discover Universe’s Largest Known Structure
Scientists have found the largest known structure in the universe, a cluster of galactic cores so vast it would take four billion years for a spacecraft traveling at the speed of light to cross it. The sighting challenges a theory from Einstein which suggests such a massive object shouldn’t exist in the universe. A quasar […]
Volunteers Help Discover Extra-Solar Planet
The recent discovery of a four-star planet highlights the growing value of citizen scientists, non-professional enthusiasts – including hobbyists, educators and amateur scientists – who participate in scientific endeavors. The discovery of the extrasolar planet dubbed PH1, which orbits twin suns and is itself orbited by a second distant pair of stars, was made through the combined efforts […]
