Einstein Proven Correct; Gravitational Waves Detected; Super Hot Planet

June 8, 2017

Einstein Theory Confirmed Again In his 1915 Theory of General Relativity, physicist Albert Einstein proposed that mass can bend space time. And he predicted that when a distant star’s light passed by a large object en route to the observer, the object’s gravity can bend and brighten the starlight like a magnifying lens. This effect, called […]

Astronomers Find a Bunch of ‘Monster Stars’ in Star Cluster

March 18, 2016

A group of astronomers probing a young star cluster within the ultraviolet section of the light spectrum just found a bunch of huge ‘monster stars.’ The R136 star cluster, located in the Tarantula Nebula, inside the Large Magellanic Cloud, is about 157,000 light years from Earth. They chose to explore in the ultraviolet range since there are […]

NASA Camera Snaps Images of the Moon Crossing Face of The Earth

August 8, 2015

Since the beginning of the space age more than 50 years ago, NASA, the U.S. space agency, has provided the world with spectacular images of our planet, solar system and universe. Now, NASA has just released an amazing ‘animated gif’ (see above) that shows the moon as it moves across of the sunlit side of […]

Artist’s impression of a black hole feasting on matter from its companion star in a binary system. Material flows from the star towards the black hole and gathers in a disc, where it is heated up, shining brightly at optical, ultraviolet and X-ray wavelengths before spiralling into the black hole.

Slumbering Giant Black Hole Awakes After 26 Years

June 27, 2015

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 […]

Planetary Scientists Get Into Balloon Game

February 10, 2014

A new device developed by NASA will help planetary scientists take advantage of high altitude research balloons, a relatively inexpensive observational platform that has long been used by other scientists. The balloons, which can climb to the edge of space, have been utilized by researchers  across multiple scientific disciplines, helping them to make groundbreaking findings. […]

Hubble Helps Astronomers Solve 40 Year-Old Mystery

August 9, 2013

Astronomers finally have been able to solve a 40-year mystery thanks to the Hubble Space Telescope. For over four decades astronomers have been trying to find the origin of the Magellanic Stream, a long ribbon of hydrogen gas clouds that stretch almost halfway around our own Milky Way galaxy. The Magellanic Stream is connected to […]

IRIS: New NASA Spacecraft to Study Mysterious Region of Sun’s Atmosphere

June 28, 2013

Did you know that the Sun’s outer atmosphere, or corona, is much hotter than its surface? Scientists have been quite curious about a mysterious interface region of the Sun’s atmosphere that amplifies energy from about 5,800 degrees Kelvin on the surface, or photosphere, to around 1,000,000 degrees Kelvin in the corona. With Thursday’s launch of […]
