New Australian infrared telescope to spot cosmic hidden treasures

 

New infrared telescope to spot cosmic hidden treasures

A new infrared telescope, to be designed and built by astronomers at The Australian National University (ANU), will monitor the entire southern sky in search of new cosmic events as they take place. DREAMS – the Dynamic REd All-Sky Monitoring Survey – will be located at the historic Siding Spring Observatory in northern New South Wales.

Half the matter in the universe was missing – we found it hiding in the cosmos

Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.

The Dinosaur-Killer Asteroid May Have Hit Earth at ‘Deadliest Possible’ Angle

 

The Dinosaur-Killer Asteroid May Have Hit Earth at ‘Deadliest Possible’ Angle

This much we knew: some 66 million years ago an asteroid roughly twice the diameter of Paris crashed into Earth, wiping out all land-dwelling dinosaurs and 75 percent of life on the planet.

Sun ‘less active’ than similar stars

The Sun is less magnetically active and shows less variability in its brightness than similar stars in the galaxy, scientists say.

To come to this conclusion, published in the journal Science, they analysed 369 candidate stars selected because they resemble the Sun in decisive properties.

“These stars appear nearly identical to the Sun except for their higher variability. Therefore, we speculate that the Sun could potentially also go through epochs of such high variability,” they write.

Promising signs for Perseverance rover in its quest for past Martian life

New research indicates river delta deposits within Mars’ Jezero crater – the destination of NASA’s Perseverance rover on the Red Planet – formed over time scales that promoted habitability and enhanced preservation of evidence.

Swift Mission Observed Water from Interstellar Comet Borisov – Astrobiology

For the first time, NASA’s Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late 2019.

“Borisov doesn’t fit neatly into any class of solar system comets, but it also doesn’t stand out exceptionally from them,” said Zexi Xing, a graduate student at the University of Hong Kong and Auburn University in Alabama who led the research. “There are known comets that share at least one of its properties.”
