Ten possible extraterrestrial technosignatures for telescopes on the Moon (The Galaxy Report)

Today’s stories include black holes that wobble three times per second, proved Einstein right when astronomers unveiled the world’s largest digital camera, and more.

One of Jupiter’s moons could hide beautiful underwater lakes – and maybe even life – Europa, a prime candidate for extraterrestrial life, has an icy surface that hides a lively, watery interior, reports Salon. “It’s important because, just as life on Earth grew out of the vast array of water-based structures on our planet, life on Europa can very well thrive in any lake system that exists on Earth. this planet.”

If Aliens Have Visited The Solar System, Here’s How To Find The Clues They Left, reports Paul Sutter for Space.com – “So far, all searches for extraterrestrial life have been unsuccessful. But there is another relatively unexplored avenue: the search for extraterrestrial artefacts (SETA). The idea behind this approach is that if aliens become advanced enough, they may want to explore the galaxy, either on their own or using robotic spacecraft over the next 4.5 billion years. history of the solar system – a long time to pass through our neighborhood and perhaps leave a mark.

Telescopes on the Moon– Our future in space hinges on colonizing the Moon and using it as a base to probe the deepest questions of the cosmos, reports Joseph Silk, Homewood Research Professor of Physics and Astronomy at Johns Hopkins University for Aeon. “Only from the lunar surface can we mount the ultimate search for our origins. We will achieve this by building new telescopes of unprecedented range into dark lunar craters and on the far side of the planet. Moon.

Black holes flickering three times per second proved Einstein right–A pair of merged black holes are showing extreme signs of gravity-induced orbital precession, or wobble, as predicted by Albert Einstein’s theory of general relativity, reports New Scientist.

NASA spacecraft accomplishes its mission and crashes an asteroid into a new orbit–The DART mission proved more successful than expected in adjusting the trajectory of Dimorphos, suggesting that a deadly space rock could be deflected in the future, The New York Times reports.

The jet of neutron stars appears to travel seven times faster than light–An optical illusion created by the relative positions of Earth and a pair of colliding neutron stars makes it look like a jet of radiation is traveling at seven times the speed of light – but thankfully, no laws of physics were broken, reports New Scientist.

James Webb Telescope captures ‘cosmic footprint’ formed by two giant stars– A series of 17 concentric dust rings were spawned by the Wolf-Rayet 140 binary system thousands of light years away, reports The Guardian. “Like a clock, WR140 inflates a sculpted ring of smoke every eight years, which is then inflated in the stellar wind like a balloon,” said Professor Peter Tuthill of the Sydney Institute for Astronomy at the University of Sydney, co- author of the study.

“We’ve never seen anything like this before: ‘Black Hole spits out material years after shredding Star, reports the Harvard CfA. The team concludes that the black hole is now ejecting matter traveling at half the speed of light, but don’t know why the exit was delayed for several years.

Astronomers have unveiled the world’s largest digital camera.– The world’s largest digital camera for astronomy is bigger than a car, has as many pixels as 266 iPhones and, over the next 10 years, will help researchers study billions of galaxies, reports New Scientist .

A black hole discovered a shooting jet on the nearby galaxy, reports the Royal Astronomical Society. The black hole is hosted by a galaxy about a billion light-years from Earth named RAD12.

Two exoplanets have a strangely heavy element floating in their skies-Astronomers have found barium floating high in the atmospheres of two sweltering exoplanets, and they don’t know how such a heavy element got where it is, reports New Scientist.
