Upcoming nova explosion in T CrB star system offers rare night sky event

In a stellar event anticipated to occur between now and September 2024, the T Coronae Borealis (T CrB) star system, located 3 000 light-years away, is predicted to undergo a nova outburst, becoming visible to the unaided eye. This rare occurrence, last witnessed in 1946, will temporarily elevate the system’s brightness to match that of the North Star, offering a unique viewing opportunity.

DART impact altered Dimorphos’ orbit and shape, proving asteroid deflection technique viable

DART impact altered Dimorphos’ orbit and shape, proving asteroid deflection technique viable

On September 26, 2022, NASA’s Double Asteroid Redirection Test (DART) mission made history by intentionally colliding with the asteroid Dimorphos, significantly altering both its orbital period and physical shape. This is the first time humanity has purposefully altered the motion of a celestial object, as well as the first full-scale demonstration of asteroid deflection technology.

Public meteorite hunt after large fireball streaks over New Zealand

Public meteorite hunt after large fireball streaks over New Zealand

A very bright fireball was seen over Otago and Canterbury, New Zealand at 08:04 UTC (21:04 LT) on March 13, 2024. Analysis shows that some 0.5 km (1.1 pounds) of the object survived the entry and ended up scattered on the ground in MacKenzie Country. A public search for meteorites is scheduled for March 21.

Giant volcano discovered in Mars’ Tharsis volcanic province

Giant volcano discovered in Mars’ Tharsis volcanic province

Scientists at the 55th Lunar and Planetary Science Conference in The Woodlands, Texas, announced the discovery of a vast volcano and a potential glacier ice sheet in Mars’ Tharsis volcanic province, near the equator. The finding, based on images from spacecraft orbiting Mars since 1971, highlights a volcano provisionally named “Noctis” and suggests the presence of glacier ice beneath a volcanic deposit. This discovery opens new avenues for studying Mars’ geological evolution and future exploration.

Largest object ever jettisoned from ISS to make uncontrolled re-entry this week

Largest object ever jettisoned from ISS to make uncontrolled re-entry this week

The International Space Station’s (ISS) largest-ever discarded object, a hefty equipment pallet weighing 2.9 tons, is anticipated to make an uncontrolled descent back to Earth between March 8 and 9, 2024. Launched into space for a critical ISS power system upgrade, this pallet, loaded with nine old station batteries, will not fully disintegrate upon reentry, with predictions indicating about half a ton of debris could survive the descent and impact the planet’s surface.

Astronomers discover oceans of water vapor in planet-forming disc around young star

Astronomers discover oceans of water vapor in planet-forming disc around young star

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered vast reservoirs of water vapor in the disc around HL Tauri, a young star 450 light-years away from Earth, unveiling processes that may lead to the birth of planets rich in water and redefining our search for life in the universe.
