Space news this week: ‘Signs of aliens’, cosmic cannibalism and the fastest-growing black hole

China says it may find signs of alien civilizations

According to a report in the state-backed Science and Technology Daily, China said its massive Giant Eye telescope may have detected signs of alien civilizations. The publication later removed the report and post about the discovery, but not before it started trending on Weibo and was picked up by various news outlets.

Sky Eye detected narrow-band electromagnetic signals that differ from previous captured signals and the team is investigating them, chief scientist of an extraterrestrial civilization discovery team co-founded by the National Astronomical Observatory of Beijing Normal University, Chinese Academy of Sciences According to Zhang Tonji of Science and the University of California, Berkeley, who was quoted by the daily.

NASA’s Persistence Rover Found a Piece of Foil on Mars

The Perseverance Mars rover captured an unexpected image with its left Mastcam-Z camera; A shiny piece of foil got stuck on a rock on a neighboring planet. The object was determined to be part of a thermal blanket that may have come from the descending stage of the rocket that lowered the rover and the Ingenuity Mars helicopter to the planet.

This is a fairly satisfactory explanation, except for one caveat: the descending stage crashed about 2 kilometers away from where the piece of foil was seen, but scientists have no explanation as to how it got there. Also, they are not sure which part of the spacecraft it came from. Currently, it is theorized that the fragment landed there during the spacecraft’s descent or was blown up there by Martian winds.

fastest growing black hole

Astronomers at the Australian National University have discovered the fastest-growing black hole ever discovered in space. According to him, the black hole is growing so fast that it consumes the equivalent of one Earth’s mass per second. The black hole is 7,000 times brighter than all the light put together in our galaxy, making it visible to astronomers across the planet.

Scientists speculate that the massive black hole formed as a result of the collision of two large galaxies. Typically, black holes form when massive stars collapse on their own, leading to supernovae. The remaining core of the star is crushed by gravity and becomes a black hole, trapping everything including light.

China’s Chang’e-5 lander finds evidence of water on the moon

Samples collected by China’s lunar lander Chang’e-5 provide the first real-time definitive confirmation of evidence of local origin water on the Moon. Chang’e-5 collected samples from the Moon’s Oceanus Procellarum, an ancient basalt mare named “Ocean of Storms”.

The water signal was first confirmed in 2021 by an on-board spectral analysis and later validated when the lander returned with laboratory tests of samples in 2021. The team later determined that the water originated from the Moon as a result of the solar wind or other external factors.

White dwarf star is ripping apart an entire planetary system in terms of “cosmic cannibalism”

The death of a star so violent that the dead star is left behind, called a white dwarf, is disrupting the entire planet’s ecosystem by sucking up debris from both its inner and outer reaches. The event also shows for the first time that a white dwarf star is consuming both rocky-metallic and icy material, both of which are “planetary constituents”.

Using data from the Hubble Space Telescope and other NASA observatories, scientists were able to diagnose this case of “cosmic cannibalism.” White dwarf stars form when low-mass stars like our Sun have exhausted most of their nuclear fuel. They are generally dense and about the size of a planet.

These findings are particularly interesting because icy objects pulled by the dwarf star are credited with crashing into and “irrigating” the dry rocky planets in the Solar System. Such comets and asteroids are believed to have brought water to Earth billions of years ago, making life possible on the planet.
