With a diameter of 1 to 2km, space rock named 2022 AP7 crosses our orbit but has ‘no chance’ of hitting Earth

Marking the passage of time in a world of ticking clocks and swinging pendulums is a simple case of counting the seconds between ‘then’ and ‘now’… however, ‘then’ can’t always be anticipated. Worse still, ‘now’ often blurs into a haze of uncertainty.

The agency released the image on Wednesday on Twitter, writing: “Today, Nasa’s Solar Dynamics Observatory caught the sun ‘smiling.’ Seen in ultraviolet light, these dark patches on the sun are known as coronal holes and are regions where fast solar wind gushes out into space.”

Last December 24, NASA’s InSight lander recorded a magnitude 4 marsquake. However, scientists only learned the cause of that quake later: a meteoroid impact estimated to be one of the biggest seen on Mars since NASA began exploring the cosmos.

A joint study by TAU and the Hebrew University, involving 20 researchers from different countries and disciplines, has accurately dated 21 destruction layers at 17 archaeological sites in Israel by reconstructing the direction and/or intensity of the earth’s magnetic field recorded in burnt remnants.

Paabo spearheaded the development of new techniques that allowed researchers to compare the genome of modern humans and that of other hominins—the Neanderthals and Denisovans.

The findings are in the latest research to be published from analysis of 5.4 grammes of stones and dust that the Hayabusa-2 probe gathered from the asteroid Ryugu.

On September 26 at 11.15 pm UTC, NASA’s DART mission (Double Asteroid Redirection Test) will be the first to deliberately and measurably change the motion of a significant body in our Solar System.

The recently launched super space telescope James Webb has returned spectacular new imagery of Neptune.

New techniques allowed researchers to analyze ancient DNA for the first time. The data they unearthed helps describe the genomic history of the area and reveals population movements from as far back as 10,000 years ago. It contains some big surprises regarding theories for the origin of languages.

You can view the virtually reconstructed face of a woman who lived about 5,700 years ago in what is now Malaysia, now that researchers have put a face to a person whose full identity remains a mystery.

The world’s most powerful telescope has made its first observations of a planet beyond our solar system, heralding a new era of astronomy in which distant worlds can be scanned for signs of life.

It isn’t alive, and has no structures even approaching the complexity of the brain, but a compound called vanadium dioxide is capable of ‘remembering’ previous external stimuli, researchers have found.

The world’s largest and most powerful space telescope has revealed unprecedented views of Jupiter.
