After investigating the nature of a mysterious and apparently cigar-shaped object called ‘Oumuamua spotted in 2017 speeding through our solar system, astronomers remain uncertain over how to classify it, but are confident it is not an alien spaceship.
Black holes have traditionally been believed to have formed exclusively from stellar remnants. New indirect evidence suggests otherwise.
NASA plans to send a drone named Dragonfly to Saturn’s biggest moon, Titan, the agency said Thursday, announcing the space agency’s latest high-profile mission to explore the solar system for clues on humanity’s origins. “Today I am proud to announce that our next New Frontiers mission, Dragonfly, will explore Saturn’s largest moon, Titan,” NASA administrator Jim Bridenstine said in a video teleconference.
Such an explosion has energy equivalent to more than 6,000 tonnes of TNT
The rings of the ice giant Uranus are invisible to all but the largest telescopes — they weren’t even discovered until 1977. However, they are surprisingly bright in the new thermal images taken by the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT). The new images allowed astronomers for the first time to measure the temperature of rings particles: minus 321 degrees Fahrenheit (minus 196 degrees Celsius).
An international team of astronomers has detected a new brown dwarf with an ultra-short orbital period that transits an active M-dwarf star. The newfound object, designated NGTS-7Ab, turns out to be the shortest period transiting brown dwarf around a main or pre-main sequence star discovered to date. The finding is detailed in a paper published June 19 on the arXiv pre-print server.
Events are planned in 192 countries, so there’s something for everyone. Jeff Glorfeld reports
A new $850 million drone-like lander will be venturing on to (and above) the surface of Saturn’s enigmatic moon.
European and U.N. bodies on Thursday outlined a joint push for global action on space junk, saying that debris orbiting the earth must be cleaned up as satellites launched by private companies and other new entrants are adding to the crowding.
It was just a couple of days ago that NASA announced something pretty exciting about Mars. Its Curiosity rover had detected shockingly high levels of methane, suggesting an unseen geological or even biological process was at work on the planet. Signs of past or present life? Perhaps, but a follow-up reading has now generated more questions than answers.
