Space Researchers Who Studied a Triple-Star System Retracted Their Paper An international team of researchers has retracted a paper published in 2016 in the Science journal. It focused on the discovery of an exoplanet in the HD 131399 triple-star system.
Space Scientists Calculated the Frequency With Which the Moon Experiences Impacts When NASA sent humans to the Moon in 1969, one of the many dangers was the risk of space rocks hitting the astronauts' spacesuits or equipment.
Space Hubble Space Telescope Captures the Galactic Angel Wing NASA shared an image captured by the Hubble Space Telescope, which shows a deep space object VV689, a system nicknamed the Angel Wing. It can be found in the night sky in the constellation Leo.
Space NASA's Perseverance Rover Reaches the Dried-up Delta of an Ancient River Delta was formed billions of years ago at the confluence of a river and crater lake. On its dried-up bottom remained clusters of rocks and prehistoric deposits. These are the best samples to study the emergence and demise of organic life.
Space Scientists Plan to Create a New Message for Intelligent Aliens The message will include information on the Earth's principles of communication, the basic mathematical and physical concepts, the structure of DNA, as well as people, and the Earth as a whole.
Space The AX-1 Mission Successfully Returned to Earth They flew more than 5 million kilometers, making about 240 orbits around the Earth. During the trip, the AX-1 mission supported 26 science payloads and technology demonstrations.
Space Elon Musk Said the Price Point for a Ticket to Mars Is Affordable for Most People The billionaire noted that the price would be based on economic feasibility. Some people might even need to sell their assets to visit Mars.
Space OneWeb Signed a Contract to Launch Satellites From India The agreement will allow OneWeb to complete a program to launch satellites and create a constellation of communication satellites in low orbit to provide high-speed connectivity with low latency.
Space NASA's Perseverance Rover Captures Solar Eclipse on Mars The footage of the solar eclipse on the Red Planet was captured on April 2 as the rover moved toward the dried-up delta of an ancient Martian river that is located near the Jezero crater.
