We Have 100 Years to Leave Earth: Stephen Hawking

Renowned physicist Stephen Hawking has warned that humanity needs to become a multi-planetary species within the next century in order to avoid extinction. Hawking made the prediction in a new documentary called Expedition New Earth, which is set to be released this summer as part of the BBC’s Tomorrow’s World science season. Existential risks include […]

Listen to the surprisingly empty gap between Saturn and its rings

Listen to the surprisingly empty gap between Saturn and its rings

Cassini made its second epic ring dive on Tuesday Saturn as seen by Cassini on May 1. NASA On Tuesday, NASA’s Cassini spacecraft dove between Saturn—the planet it’s spent years studying—and the gas giant’s rings. This was the second of 22 such maneuvers, the last of which will send Cassini careening into Saturn’s atmosphere to […]

A warp in space-time just gave us four views of one exploding star

A warp in space-time just gave us four views of one exploding star

Astronomers catch a galaxy magnifying and splitting the light from a supernova ESA/Hubble, NASA Like a lens, a galaxy (center, blue) passing in front of a supernova has split its light into four images (yellow/orange), and magnified its intensity by 52 times. Although the night sky often seems so peaceful and still, a closer look […]

Risk, Reward, Regulation and Space Tourism

Risk, Reward, Regulation and Space Tourism

. By Thomas L. Knapp Writing at Quartz, Tim Fernholz notes that early space tourists “won’t benefit from the tight regulation we’ve come to expect in everything from air transport to private automobiles.” Although the Federal Aviation Administration enjoys approval authority over launches, the Commercial Space Act limits government interference in post-launch space flight. That’s […]

Earth Science on the Space Station Continues to Grow

Earth Science on the Space Station Continues to Grow

The number of instruments on the International Space Station dedicated to observing Earth to increase our understanding of our home planet continues to grow. Two new instruments are scheduled to make their way to the station Feb. 18 on the SpaceX Dragon capsule. The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument will monitor the […]

Scientists spotted a supernova just hours after it exploded

Scientists spotted a supernova just hours after it exploded

Its dying gasps could reveal what makes stars go out with a bang Ofer Yaron Artist illustration of the supernova SN 2013fs, located in a nearby galaxy. Talk about going out with a bang. Stars that are about 10 times more massive than the Sun tend to die in colossal explosions called supernovae. Scientists aren’t […]

‘Dominated By America’: How Trump Wants To Send NASA Back To The Moon And Mars

President Donald Trump is planning to return U.S. astronauts to the moon by 2020 and go onto Mars soon after, according to leaked internal documents. The documents say Trump wants NASA to launch a “rapid and affordable” lunar mission to the moon by 2020, build privately operated space stations and assist “the large-scale economic development […]

Today’s rarest space rocks were once the most common

Today’s rarest space rocks were once the most common

Unfortunately for us, meteorites still come in all shapes and sizes Don Davis, Southwest Research Institute Asteroid Collision A collision 466 million years ago gave rise to many of the meteorites falling today. The history of our solar system is a history of collisions. Massive, world-shattering collisions. Evidence of these collisions rains down on us […]
