Hubble Zooms in on Shrapnel from an Exploded Star
NASA’s Hubble Space Telescope has unveiled in stunning detail a small section of the expanding remains of a massive star that exploded about 8,000 years ago.

Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan.

R.I.P. Cassini

PASADENA, Calif. — Cassini went down fighting.

After 20 years in space and 13 years orbiting Saturn, the veteran spacecraft spent its last 90 seconds or so firing its thrusters as hard as it could to keep sending Saturnian secrets back to Earth for as long as possible.

The spacecraft entered Saturn’s atmosphere at about 3:31 a.m. PDT on September 15 and immediately began running through all of its stabilizing procedures to try to keep itself upright. The signal that Cassini had reached its destination arrived at Earth at 4:54 a.m., and cut out about a minute later as the spacecraft lost its battle with Saturn’s atmosphere.

“The signal from the spacecraft is gone, and within the next 45 seconds, so will be the spacecraft,” Cassini project manager Earl Maize announced from the mission control center at NASA’s Jet Propulsion Lab. “I hope you’re all as deeply proud of this amazing accomplishment. Congratulations to you all. This has been an incredible mission, an incredible spacecraft, and you’re all an incredible team. I’m going to call this the end of mission. Project manager, off the net.”

With that, the mission control team erupted in applause, hugs and some tears.

Meet the Hubble repairman

Why do we still get Hubble space images years past the orbiting telescope's life expectancy? Astronaut John Grunsfeld has something to do with it

The Hubble Space Telescope, launched in 1989, was supposed to last 15 years. But the remarkable scientific instrument is still pumping out intense, revealing images from across the universe 27 years later thanks to a dedicated astronaut who has risked his life to repair it three times. Bill Whitaker reports on the fantastic images still amazing scientists and speaks to astronaut John Grunsfeld – dubbed the "Hubble repairman" – on 60 Minutes, Sunday, Oct. 1 at 7:30 p.m. ET and 7 p.m. PT.

Grunsfeld tells Whitaker he's confident the Hubble Space Telescope will continue to function another three to five years. But another telescope, larger and expected to be even more revealing than Hubble, is set to be launched in 2019 that will eventually take the Hubble's place. This excites Grunsfeld.
