From solar flares to black hole jets: NASA’s Fermi Gamma-ray Space Telescope team has produced a unique time-lapse tour of the dynamic high-energy sky. Fermi Deputy Project Scientist Judy Racusin narrates the movie, which compresses 14 years of gamma-ray observations into 6 minutes.

This new image of NGC 2264, also known as the “Christmas Tree Cluster,” shows the shape of a cosmic tree with the glow of stellar lights. NGC 2264 is, in fact, a cluster of young stars — with ages between about one and five million years old — in our Milky Way about 2,500 light-years away from Earth. The stars in … Read more
2 min read Cosmic Companionship Quest Marks Major Milestone Are we alone in the universe? About 30,000 volunteers want to know! These volunteers visited arewealone.earth to sift through a huge data set from the 100 meter Green Bank Telescope—inspecting it for signals that might indicate intelligent extraterrestrial life. As of this week, this giant team has made ONE … Read more
To ensure it can withstand the rattling it will experience at launch, the mission team transported BurstCube to Washington Laboratories in Frederick, Maryland, for vibration testing. Engineers strapped the satellite to a plate, which then vibrated at frequencies ranging from 20 to 20,000 hertz. Translated into sound, that spans bass to the upper limit of … Read more
In March 2017, NASA Astrophysics Division selected the Explorer Mission of Opportunity GUSTO (Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory) to measure emissions from the interstellar medium to help scientists determine the life cycle of interstellar gas by surveying a large region of our Milky Way galaxy and the Large Magellanic Cloud. The GUSTO mission is led … Read more
Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star. At the low end of the scale, some brown dwarfs are comparable … Read more
At 1 a.m. on December 18, 1993, about a week after the mission had ended, astronomers gathered around computers at the Space Telescope Science Institute in Baltimore to witness the first new image from the telescope: a star, shining clear and pristine in the image without the hazy effects of Hubble’s flawed mirror. The new … Read more
It was subsequently shown that the original Abell cluster is actually comprised of two independent galaxy clusters – a foreground group around 2.3 billion light-years from Earth, and another group at the greater distance of about 5.4 billion light-years from our planet. The more distant galaxy cluster, included in the Massive Cluster Survey as MCS … Read more
The team is now running tests to characterize the issue and develop solutions. If necessary, the spacecraft can be re-configured to operate with only one gyro. The spacecraft had six new gyros installed during the fifth and final space shuttle servicing mission in 2009. To date, three of those gyros remain operational, including the gyro … Read more
This visualization shows 294 gamma-ray pulsars, first plotted on an image of the entire starry sky as seen from Earth and then transitioning to a view from above our galaxy. The symbols show different types of pulsars. Young pulsars blink in real time except for the Crab, which pulses slower than in real time because … Read more
