A 'city-killer' asteroid might hit Earth -- how worried should we be?
A colossal explosion in the sky, unleashing energy hundreds of times greater than the Hiroshima bomb. A blinding flash nearly as bright as the Sun. Shockwaves powerful enough to flatten everything for miles.
It may sound apocalyptic, but a newly detected asteroid nearly the size of a football field now has a greater than one percent chance of colliding with Earth in about eight years.
Su SpaceX launches more Startlink satellites from California
SpaceX launched 22 more Starlink satellites, this time from Vandenberg Space Force Base in California.
A Falcon 9 rocket lifted off from pad 4E at 3:02 p.m. PST Saturday.
About eight minutes later, the first stage returned to Earth and touched down in the Pacific Ocean on the SpaceX's drone ship "Of Course I Still Love You."
The upper stage carried the satellites to low Ea Fifth H-3 rocket successfully launches Michibiki No. 6 satellite
The Japan Aerospace Exploration Agency (JAXA) successfully launched its fifth H-3 rocket on Sunday, carrying the Michibiki No. 6 satellite, a key addition to Japan's independent positioning system. The rocket lifted off from Tanegashima Space Center in Kagoshima Prefecture at 5:30 p.m. local time and successfully deployed its payload into the designated orbit.
The Michibiki satellite ser
Caltech takes first steps toward lightsails that could reach distant star systems
The idea of traveling through interstellar space using spacecraft propelled by ultrathin sails may sound like the stuff of sci-fi novels. But in fact, a program started in 2016 by Stephen Hawking and Yuri Milner known as the Breakthrough Starshot Initiative has been exploring the idea. The concept is to use lasers to propel miniature space probes attached to "lightsails" to reach ultrafast speed Top 10 persistent methane sources
A list of the top 10 global regions where natural or anthropogenic sources emit methane on a continuous, ‘persistent’ basis was recently published in a scientific journal.
60 days in bed for science

00:06:40
A group of volunteers is spending two months lying in bed—with their feet up and one shoulder always touching the mattress—even while eating, showering, and using the toilet. But why? This extreme bedrest study is helping scientists understand how space travel affects the human body and how to keep astronauts healthy on long missions.
Microgravity causes muscle and bone loss, fluid shifts, and other physiological changes similar to those experienced by bedridden patients on Earth. By studying volunteers here on Earth, researchers can develop better countermeasures for astronauts and even improve treatments for medical conditions like osteoporosis.
