The so-called Hycean planet K2–18 b is around twice the size of Earth and orbits in the habitable zone of a star located 120 light-years from our solar system.
The space telescope seems to have detected dimethyl sulfide (DMS), which on Earth is only produced as a by-product of life, mainly created by phytoplankton. The team is cautious about this detection, which is far less certain than the presence of carbon molecules.
Teams at the NASA Michoud Assembly Facility have structurally joined all four RS-25 engines onto the core stage for NASA's Space Launch System rocket that will send four astronauts on their journey around the Moon during #Artemis II.
Technicians will now focus on the complex task of fully securing the engines to the stage and integrating the propulsion and electrical systems within the structure.
While using ground-based telescopes to hunt for fresh targets for NASA’s New Horizons spacecraft, now past Pluto on a course out of the Solar System, Fraser and his colleagues have made a tantalizing, though preliminary, discovery: about a dozen objects that lie beyond 60 AU—nearly as far from Pluto as Pluto is from the Sun. The finding, if real, could suggest that the Kuiper belt either extends much farther than once thought or—given the seeming 10-AU gap between these bodies and the known Kuiper belt—that a “second” belt exists.
In a study published in Nature Astronomy, astronomers from New Jersey Institute of Technology's Center for Solar-Terrestrial Research (NJIT-CSTR) have detailed radio observations of an extraordinary aurora-like display occurring 40,000 km above a relatively dark and cold patch on the sun, known...
"We've detected a peculiar type of long-lasting polarized radio bursts emanating from a sunspot, persisting for over a week," said Yu. "This is quite unlike the typical, transient solar radio bursts typically lasting minutes or hours. It's an exciting discovery that has the potential to alter our comprehension of stellar magnetic processes."
The Curiosity rover's wheels after 10 years on the rugged Martian terrain.
Curiosity has 6 wheels, each about 20 inches (50 centimetres) in diameter. The wheels are made of aluminium and have cleats for traction and curved titanium spokes for springy support. This thin and unique design helps the rover move over rocks and sandy surfaces, while the flexible spokes minimize damage from the rugged landscape.
An interesting aspect of Curiosity's wheels is the special pattern of holes they have. As the rover moves, these holes imprint a pattern on the Martian surface, spelling out "JPL" (Jet Propulsion Laboratory) in Morse code, the NASA centre responsible for the rover.
