A huge asteroid, known as 2021 KT1, will make a "close approach" to Earth on June 1 at about 10:24 am EDT, according to NASA.
Since 2013, NASA has been leading exercises in which experts confront a fictitious Earth-bound asteroid. The outcomes are grim.
In a recent NASA simulation, scientists had six months to stop a hypothetical asteroid from hitting Earth, and they failed. That wasn't enough time.
On Friday night, the asteroid Apophis will pass by Earth. When it returns in 2029, its orbit may put it on a collision path with some satellites.
Astronomers discovered a planetoid orbiting the sun further than any known object in the solar system. Called “Farfarout,” the object orbits the sun every 1,000 years. Objects like Farfarout could help astronomers figure out whether a massive planet hides in the outskirts of our solar system. Visit the Business section […]
In 2020, SpaceX became the first private company to launch humans into orbit, Japan brought asteroid samples to Earth, and China’s landed a spacecraft on the moon. But 2021 is set to be an even more ambitious year in space, with rovers set to land on Mars, new commercial astronaut […]
The Arecibo Telescope collapsed on Tuesday: Its 900-ton hanging platform crashed into its main dish. In its 57 years of radio astronomy, Arecibo tracked potentially hazardous asteroids, discovered the first exoplanet, and broadcast a message for aliens. The telescope even starred in a James Bond film and the movie “Contact.” […]
The Arecibo Observatory’s iconic radio telescope collapsed Tuesday morning. The telescope’s suspended platform, which weighed 900 tons, crashed into its bowl-shaped disk below. The tops of three support towers snapped off as the platform fell. Arecibo’s destruction was not unexpected: The telescope was damaged beyond repair after two cables broke […]
The Arecibo Observatory’s iconic 1,000-foot radio telescope has been damaged beyond repair after two destructive cable breaks. If another cable fails, the telescope’s 900-ton platform would crash into its disk and could pull down three towers with it. Engineers are racing to deconstruct the telescope before it catastrophically collapses. The […]
The Arecibo Observatory is a radio telescope that hunts for hazardous asteroids and helps scientists search for alien life. It just suffered its second catastrophic cable break in just three months. In August, an auxiliary cable broke and tore a hole into the observatory’s reflector dish. On Friday, a cable […]
NASA’s OSIRIS-REx spacecraft is set to land on asteroid Bennu and collect samples of rock on Tuesday evening. The van-sized probe will have to manoeuvre past a rock field to land on a small, smooth stretch of the asteroid’s surface. Live coverage of the manoeuvre begins at 5 p.m. ET […]
An asteroid the size of a car flew within about 1,830 miles of Earth this weekend – closer than any known space rock has ever come without crashing into the planet. A NASA-funded program detected the asteroid, called 2020 QG, six hours after its close approach. If the asteroid had […]
Comet Neowise has dazzled stargazers this week, but its surprise appearance highlights one of Earth’s greatest vulnerabilities. NASA discovered the comet hurtling towards Earth three months ago, but only because one of its space telescopes got lucky. Our planet is woefully unprepared for the enormous, deadly rocks that hurtle towards […]
NASA‘s Hubble Space Telescope has snapped a clear photo of the second interstellar visitor ever detected in our solar system. The comet, called 2I/Borisov, came from an unknown star system. It’s hurtling past the sun at 110,000 miles per hour and is expected to pass close to Mars later this […]
Astronomers have detected an interstellar object approaching our solar system. Called “2I/Borisov” (formerly “C/2019 Q4” or “gb00234”), the object appears to be following a path originating from outside the solar system. It’s expected to pass near Mars in October. This is the second interstellar object ever observed in our solar […]
NASA has big plans for this new decade: The agency is working to send humans back to the moon and search for life near Saturn. NASA’s 10-year plan also includes missions to probe the metal core of a dead planet, photograph the Big Bang, and scan for aliens in a […]
Earth’s moon may be hiding a giant metallic lump beneath an impact crater called the South Pole-Aitken Basin. The feature may be the core of an asteroid or planetary chunk, or possibly a frozen ocean of magma. The mysterious object is about five times the size of the Big Island […]
