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 […]
Mars has a series of saltwater lakes beneath the glaciers of its southern ice cap, researchers say. These hypersalty patches of liquid water could harbour microbial alien life. NASA’s Perseverance rover is travelling to Mars to search for signs of extraterrestrial life. Visit Business Insider’s homepage for more stories. Scientists […]
A NASA spacecraft has discovered that a saltwater ocean lies deep below the surface of Ceres, a dwarf planet in the asteroid belt between Mars and Jupiter. New research shows that shiny salt deposits on Ceres’ surface were left by water percolating up from underground. Ceres may have once held […]
Astronomers have discovered a new Earth-sized planet outside our solar system, 100 light-years away. The planet, named TOI 700 d, is in its star’s habitable zone and has the potential to hold liquid water. Future research could give scientists more information about the planet’s surface and atmosphere. Visit Business Insider’s […]
100 red objects in deep space seem to have mysteriously vanished over the last 70 years. Researchers say the objects could be lasers that aliens use to communicate across interstellar space, or stars that aliens covered with huge megastructures. The objects could also be the first evidence ever of “failed […]
A new space telescope launched into Earth orbit Wednesday morning. The characterising ExOPlanets Satellite (CHEOPS) was originally scheduled to launch on Tuesday, but the launch sequence was interrupted just 1 hour and 25 minutes before liftoff. The telescope is expected to take an unprecedented look at planets outside our solar […]
A handful of recent discoveries indicate that Earth-like planets are common in the Milky Way. NASA’sKepler space telescope spurred new research into planets outside our solar system. There could be up to 10 billion Earth-like planets in our galaxy alone – and they may be even more similar to our […]
NASA began testing an alien-hunting underwater rover in Antarctica this week. The robot, called the Buoyant Rover for Under-Ice Exploration (BRUIE), rolls along the bottom of ice sheets in polar oceans, scanning for signs of life. BRUIE is built for the hidden subsurface seas of distant ice worlds like Europa […]
Many things that are reported as UFOs turn out not to be extraterrestrial at all. The Lockheed F-117 and the SR-71 Blackbird jets both had designs that looked otherworldly. A natural phenomenon called ball lightning has also led witnesses to think they’d seen something alien. Mundane objects such as paper […]
NASA has picked a landing site for its upcoming Mars 2020 rover. The space agency will try to land its nuclear-powered robot in Jezero Crater, a giant impact near the Martian equator. Jezero Crater was a water-rich area billions of years ago on Mars, and it might still hide signs […]
Astronomers think they have found a “cold super-Earth” exoplanet orbiting Barnard’s star. Barnard’s star, less than six light-years from us, is the closest single-star system to our sun. The new world, called Barnard’s star b, or GJ 699 b, is at least 3.2 times as massive as Earth. It orbits […]

NASA launched an ion-propelled probe called Dawn toward the asteroid belt in 2007. In 2015, Dawn reached Ceres, a Texas-sized dwarf planet that may hide a salty ocean and possibly alien life. The spacecraft is almost out of fuel, and its mission may end between mid-September and mid-October. Researchers expect […]
NASA launched a new planet-hunting space telescope in April using a SpaceX rocket. The Transiting Exoplanet Survey Satellite (TESS), as the spacecraft is called, could discover thousands of worlds fairly close to Earth. Scientists also expect to find about 50 small, rocky planets that may be habitable to alien life. […]
The moon could have supported life twice in its history, according to a new study. It’s possible that 4 billion and 3.5 billion years ago, the moon had liquid water, an atmosphere, and a magnetic field. It could have even had organic material. These conditions may have lasted for tens […]
Nearly half of Americans believe aliens have visited Earth, according to a poll. The Drake equation explores the chances that detectable alien civilizations exist using seven variables. While some predictions that use the equation are optimistic, a comprehensive new study suggests a strong likelihood that we’re alone in the Milky […]
Enceladus, an ice-encrusted moon of Saturn, hides an ocean of saltwater that blasts ice into space. NASA flew its Cassini spacecraft through the ice geysers in 2015. Scientists continue to analyse the data, and on Wednesday a group announced that it had detected complex organic molecules. Though not definitive proof […]
Elon Musk says we need to colonize space because we may be the only intelligent civilisation. His comments were inspired by a draft study from Oxford University researchers that looks at the Drake equation, a formula that explores the possibility of other intelligent alien life in our galaxy. The research […]
An important existential question about human survival is also relevant to the search for alien life: Is it possible for a civilisation to survive long enough to explore the stars? A new paper suggests there are four pathways a civilisation could follow as it develops. On three of those paths, […]
NASA’s New Frontiers program is a competition for scientists to get their space mission funded. The winner, to be selected in 2019, will get funding and a rocket launch that are valued at a combined $US1 billion. On Wednesday, the space agency is revealing its top finalists. The teams competing […]
NASA, in partnership with Google, has discovered two new planets orbiting sun-like stars. One of the new planets, Kepler 90i, is the eighth planet orbiting its star – making that solar system the only one known to have as many planets as ours. Astronomers who study Kepler exoplanet data applied […]
NASA is announcing a new discovery on Thursday at 1 p.m. ET. Astronomers who study Kepler exoplanet data and an engineer from Google Brain are involved in the announcement. Documents shared by NASA Watch describe a method for using Google’s artificial intelligence algorithms to identify planets in Kepler space telescope […]
NASA’s 20-year Cassini mission ended in September, when the probe plunged into Saturn. The spacecraft sent back a remarkable last batch of images during its grand finale. A new composite image shows a stunning view of Saturn as a final farewell to the planet. On September 15, NASA’s 20-year, $US3.26 […]
