NASA - National Aeronautics and Space AdministrationWashington, D.C. – The Universe is a big place, full of unknowns. Astronomers using NASA’s Chandra X-ray Observatory have just catalogued a new one.

“I couldn’t believe my eyes,” says Esra Bulbul of the Harvard Center for Astrophysics. “What we found, at first glance, could not be explained by known physics.”

Together with a team of more than a half-dozen colleagues, Bulbul has been using Chandra to explore the Perseus Cluster, a swarm of galaxies approximately 250 million light years from Earth.

NASA looks back at the July 2012 Solar Superstorm that just missed Earth

NASA - National Aeronautics and Space AdministrationWashington, D.C. – If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news.

Two years ago, Earth experienced a close shave just as perilous, but most newspapers didn’t mention it. The “impactor” was an extreme solar storm, the most powerful in as much as 150+ years.

“If it had hit, we would still be picking up the pieces,” says Daniel Baker of the University of Colorado.

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed.

The pulsar’s radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by NASA’s Fermi Gamma-ray Space Telescope.

NASA - National Aeronautics and Space AdministrationPasadena, CA – As the European Space Agency’s spacecraft Rosetta is slowly approaching its destination, comet 67P/Churyumov-Gerasimenko, the comet is again proving to be full of surprises.

New images obtained by OSIRIS, the onboard scientific imaging system, confirm the body’s peculiar shape hinted at in earlier pictures. Comet 67P is obviously different from other comets visited so far.

The images show that comet 67P/Churyumov-Gerasimenko has a two-part shape. (ESA/Rosetta/MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA)

NASA - National Aeronautics and Space AdministrationPasadena, CA – Flashes appear on a baseball-size Martian rock in a series of images taken Saturday, July 12th by the Mars Hand Lens Imager (MAHLI) camera on the arm of NASA’s Curiosity Mars Rover. The flashes occurred while the rover’s Chemistry and Camera (ChemCam) instrument fired multiple laser shots to investigate the rock’s composition.

ChemCam’s laser has zapped more than 600 rock and soil targets on Mars since Curiosity landed in the planet’s Gale Crater in August 2012.

Written by Tony Phillips

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In July 2015, NASA will discover a new world. No one knows what to expect when the alien landscape comes into focus. There could be icy geysers, towering mountains, deep valleys, even planetary rings.

At this point, only one thing is certain: Its name is Pluto.

On July 14th, 2015, NASA’s New Horizons spacecraft will make a close flyby of that distant world.

NASA’s prepares for Next Giant Leap, Mars and Beyond

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The first humans who will step foot on Mars are walking the Earth today. It was 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era.

We stand on a new horizon, poised to take the next giant leap—deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond.
