Changes on 55 Cancri e

For the first time, researchers led by the University of Cambridge have detected atmospheric variability on a rocky planet outside the solar system, and observed a nearly threefold change in temperature over a two year period.

Akari View of the Cygnus Region of the Milky Way

The constellation of Cygnus is one of the most recognisable in the northern hemisphere. During the summer months, the stars of its long neck stretch along the Milky Way and its wings sweep from side to side.


High School Students Find Pulsar With Widest Orbit Ever Detected

High School Students Find Pulsar With Widest Orbit Ever Detected

A team of highly determined high school students discovered a never-before-seen pulsar by painstakingly analyzing data from the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT).


The Pillars of Creation Revealed in 3-D

The Pillars of Creation Revealed in 3-D Video in Story

Using the MUSE instrument on ESO's Very Large Telescope (VLT), astronomers have produced the first complete three-dimensional view of the famous Pillars of Creation in the Eagle Nebula, Messier 16.


NuSTAR Captures Possible 'Screams' from Zombie Stars

NuSTAR Captures Possible 'Screams' from Zombie Stars

Peering into the heart of the Milky Way galaxy, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has spotted a mysterious glow of high-energy X-rays that, according to scientists, could be the "howls" of dead stars as they feed on stellar companions.


Hubble's 25th Anniversary Tribute

Hubble's 25th Anniversary Tribute Video in Story

During a program at the Smithsonian's National Air and Space Museum in Washington, the Astronauts, scientists, engineers, technicians, educators, and staff who have contributed to Hubble's success were honored, followed by talks from prominent officials whose significant contribution to space science have made Hubble possible. April 24 marks the 25th anniversary of the launch of the Hubble Space Telescope.


The Most Comprehensive Map of the Universe

The Most Comprehensive Map of the Universe

Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood to date.

Official Hubble 25th Anniversary Image Unveiled Video in Story

The official Hubble 25th anniversary image was unveiled during a program at the Newseum in Washington, DC. Remarks were made by NASA Administrator Charlie Bolden, Associate Administrator for the Science Mission Directorate John Grunsfeld and others. April 24 marks the 25th anniversary of the launch of the Hubble Space Telescope.


Astronomers Find Runaway Galaxies

Astronomers Find Runaway Galaxies

We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.


Clusters of Monster Stars Lit up the Early Universe

Clusters of Monster Stars Lit up the Early Universe

The first stars in the Universe were born several hundred million years after the Big Bang, ending a period known as the cosmological 'dark ages' when atoms of hydrogen and helium had formed, but nothing shone in visible light.


Researchers Create Comb that Detects Terahertz Waves With Extreme Precision

Researchers Create Comb that Detects Terahertz Waves With Extreme Precision

Light can come in many frequencies, only a small fraction of which can be seen by humans. Between the invisible low-frequency radio waves used by cell phones and the high frequencies associated with infrared light lies a fairly wide swath of the electromagnetic spectrum occupied by what are called terahertz, or sometimes submillimeter, waves.


First Exoplanet Visible Light Spectrum

First Exoplanet Visible Light Spectrum

The exoplanet 51 Pegasi b lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found orbiting an ordinary star like the Sun.


Black Hole Hunters Tackle a Cosmic Conundrum

Black Hole Hunters Tackle a Cosmic Conundrum

Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.


A Cold Cosmic Mystery Solved

A Cold Cosmic Mystery Solved

In 2004, astronomers examining a map of the radiation leftover from the Big Bang (the cosmic microwave background, or CMB) discovered the Cold Spot, a larger-than-expected unusually cold area of the sky.


Inner Region of Young Star and its Planets Probed

Inner Region of Young Star and its Planets Probed

Astronomers have probed deeper than before into a planetary system 130 light-years from Earth.


Death Of Giant Galaxies Spreads From The Core

Death Of Giant Galaxies Spreads From The Core

Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago.
