On October 27, 2020, at 4:40 EDT (1:40 p.m. PDT), NASA’s Mars 2020 spacecraft, which includes the Perseverance rover and the Ingenuity helicopter, reached its halfway point — 235.4 million km (146.3 million miles) — on its journey to Mars.
NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) observed the hyperactive Jupiter-family comet 46P/Wirtanen as it made its closest approach to Earth in December 2018. Now the latest analysis of SOFIA’s data reveals that water in hyperactive comets may share a common origin with Earth’s oceans, reinforcing the idea that comets played a key role in bringing water to our planet billions of years ago.
InSight will tell us about the planet’s interior, but it’s got to stick the landing first.
Six years after last landing on Mars, NASA is sending a robotic geologist to dig deeper than ever before to take the planet’s temperature.
Landing on Mars is difficult and not always successful.
Antarctica is a weird place.
Surface features on Ceres—the largest world between Mars and Jupiter—and its interior evolution have a closer relationship than one might think.
Black holes are famous for being ravenous eaters, but they do not eat everything that falls toward them. A small portion of material gets shot back out in powerful jets of hot gas, called plasma, that can wreak havoc on their surroundings. Along the way, this plasma somehow gets energized enough to strongly radiate light, forming two bright columns along the black hole’s axis of rotation. Scientists have long debated where and how this happens in the jet.
NASA’s Cold Atom Lab Aboard the ISS Will Reshape Our Understanding of Matter and Gravity
