Analysis of dinosaur eggshells: Bird-like Troodon laid 4 to 6 eggs in a communal nest      (via sciencedaily.com) 

An international research team has determined that Troodon, a dinosaur very close to modern birds, was a warm-blooded animal (an endotherm), but had a reproductive system similar to that of modern reptiles. The scientists applied a new method which allowed for accurate determination of the temperature when the egg's carbonate shell was formed. Furthermore, the researchers showed that Troodon laid 4 to 6 eggs per clutch. As nests with up to 24 Troodon eggs had been found, the scientists conclude that several Troodon females laid their eggs in communal nests.

AI algorithm unblurs the cosmos      (via sciencedaily.com) 

Researchers adapted a well-known computer-vision algorithm used for sharpening photos and, for the first time, applied it to astronomical images from ground-based telescopes. While astrophysicists already use technologies to remove blur, the adapted AI-driven algorithm works faster and produces more realistic images than current technologies. The resulting images are blur-free and truer to life.

Scientists observe flattest explosion ever seen in space      (via sciencedaily.com)     Original source 

Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.

Predatory dinosaurs such as T. rex sported lizard-like lips      (via sciencedaily.com) 

A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.

Astronomers witness the birth of a very distant cluster of galaxies from the early Universe      (via sciencedaily.com)     Original source 

Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.

How cosmic winds transform galactic environments      (via sciencedaily.com)     Original source 

Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds -- high-powered streams of charged particles and gases -- can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.

Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions      (via sciencedaily.com) 

Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.

Redness of Neptunian asteroids sheds light on early Solar System      (via sciencedaily.com) 

Asteroids sharing their orbits with the planet Neptune have been observed to exist in a broad spectrum of red color, implying the existence of two populations of asteroids in the region, according to a new study by an international team of researchers.

Temperature of a rocky exoplanet measured      (via sciencedaily.com) 

An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has no significant atmosphere.

Two meteorites are providing a detailed look into outer space      (via sciencedaily.com) 

If you've ever seen a shooting star, you might have seen a meteor on its way to Earth. Those that land here can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Scientists have conducted some of the most detailed analyses yet on the organic material of two meteorites.

Surprisingly simple explanation for the alien comet 'Oumuamua's weird orbit      (via sciencedaily.com) 

When the first interstellar comet ever seen in our solar system was discovered in 2017, one characteristic -- an unexplained acceleration away from the sun -- sparked wild speculation, including that it was an alien spacecraft. An astrochemist found a simpler explanation and tested it with an astronomer: in interstellar space, cosmic rays converted water to hydrogen in the comet's outer layers. Nearing the sun, outgassed hydrogen gave the tiny comet a kick.

Searching for life with space dust      (via sciencedaily.com) 

Following enormous collisions, such as asteroid impacts, some amount of material from an impacted world may be ejected into space. This material can travel vast distances and for extremely long periods of time. In theory this material could contain direct or indirect signs of life from the host world, such as fossils of microorganisms. And this material could be detectable by humans in the near future, or even now.
