Gamma Ray All-Sky Map

The Fermi Gamma-ray Space Telescope is our high energy eye in orbit keeping a look out for big events in the universe and creating an extensive detailed map in the process. A high energy map of our universe reveals many interesting objects such as pulsars, super-massive black holes and possibly clues to its beginning.

Perfect Spheres to Test Einstein

Einstein is looking at you through a near perfect glass sphere. In fact this is the most precise sphere that humans have ever created. The surface of this little marble is so smooth that any bumps or scratches are no higher than 40 atoms. Cool! But why?

Dust devils on Mars!

What does this image look like to you? Could it be a close up of a tattoo or a lizard's back or even silly putty that was rubbed on a news paper?

Exploding White Dwarf Star

Astrophysicists are able to "explode a star" in a virtual computational laboratory by applying physics to calculate the mechanism and progression of the explosion.

Relativity Train

This train has endured space and time to teach physics to those wandering through the Bolivian desert.

Supernovae Surprise

There's no avoiding the tragic end of a large star's life: it dies in a catastrophic explosion called a supernova.

Red Rover, Red Rover

With dwindling hope, scientists with the European Space Agency have awaited a nine-note musical message, much like the sound I hear on my daughter's cellphone when it receives a call.

Thanks for the Memories

On September 21, 2003 the spacecraft Galileo ended a 14-year mission exploring Jupiter and its four largest moons

Structures of the Early Universe

Enormous structures in the early universe which are invisible to the unaided eye become apparent when observed using a telescope sensitive to mm-wave light.

Twinkle, Twinkle, Little Tadpole

Against a stunning backdrop of thousands of galaxies, this odd-looking galaxy with the long streamer of stars appears to be racing through space, like a runaway pinwheel firework.

High-Speed Chase

Relativity theory insists that no matter what speed you choose for your spaceship--snail-like or close to light speed--the laws of physics always look the same.

Galaxies Galore

Astronomers at the Space Telescope Science Institute today unveiled the deepest portrait of the visible universe ever achieved by humankind.

Plasma Jets

From the surface of the sun to the violent cores of quasars, many astrophysical objects shoot plasma in sharply defined streams, guided by magnetic fields.

Photonic Phocus

Astronomers at the Space Telescope Science Institute today unveiled the deepest portrait of the visible universe ever achieved by humankind.

Wholly Ozone

According to recent research, cosmic rays may be enlarging the hole in the ozone layer.

Corona... Gasp!

In late October 2002, the time that some parts of the world were observing autumn’s explosion of color, the Sun gave a colorful show of its own to solar physicists.
