USTC detects a sharp rise in detection rate of broad absorption line variations

Gas around black holes and interstellar medium distribution are key factors in understanding the growth of supermassive black holes and the evolution of their host galaxies. However, as a crucial parameter, gas density is hard to be determined reliably, because the general method is not applicable to all quasars.
Researchers from the University of Science and Technology of China (USTC) of Will this solve the mystery of the expansion of the universe
Write a comment
The universe was created by a giant bang; the Big Bang 13.8 billion years ago, and then it started to expand. The expansion is ongoing: it is still being stretched out in all directions like a balloon being inflated.
Physicists agree on this much, but something is wrong. Measuring the expansion rate of the universe in different ways leads to different results.
So, is something wrong New 'Eyewear' to Deepen the View of NASA's Roman Space Telescope

NASA's Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening up exciting new opportunities for discoveries from the edge of our solar system to the farthest reaches of space.

Some observatories - like the recently collapsed Arecibo Telescope in Puerto Rico - examine nearby objects by bouncing radio light off of them. A new study has now improved how we analyze these observations to learn about near-Earth asteroids.
There's plenty we can learn about the universe from passive radio astronomy, in which we observe the radio signals emitted by distant sources. But w Women making the Webb Space Telescope a reality

On the occasion of International Women’s Day 2021, and as excitement builds for the launch of the James Webb Space Telescope (Webb) in October, ESA is highlighting women that play an important role in Europe’s contribution to Webb.
An astronaut’s guide to out-of-Earth manufacturing
Write a comment
Improvising new stuff from the stuff you have is part of an astronaut’s job description – think Apollo 13’s crew refitting CO2 filters to save their own lives, or stranded Mark Watney in The Martian, feeding himself on the Red Planet. Now plans are underway to manufacture items in orbit, and ESA astronaut Alexander Gerst argues this could make a big difference to living and working in space.

NASA's new Mars rover hits dusty red road, 1st trip 21 feet
Write a comment
NASA's newest Mars rover hit the dusty red road this week, putting 21 feet on the odometer in its first test drive.
The Perseverance rover ventured from its landing position Thursday, two weeks after setting down on the red planet to seek signs of past life.
The roundabout, back and forth drive lasted just 33 minutes and went so well that more driving was on tap Friday and Saturday for the the six-wheeled rover.
"This is really the start of our journey here," said Rich Rieber, the NASA engineer who plotted the route.
DcubeD to release its new deployable SPACE SELFIE STICK (D3S3)

DcubeD (Deployables Cubed GmbH) has released its first ever deployable structure product, the "DCUBED SPACE SELFIE STICK", shortened to D3S3. The Space Selfie Stick will be launched into space onboard a SpaceX Falcon 9 rocket in June 2021 as part of an In-Orbit Demonstration Mission in partnership with the Polish satellite manufacturer Sat Revolution and the British New Space propulsion develope Sixth mirror casting brings Giant Magellan Telescope closer to completion

At 3 p.m. on March 5, a gigantic furnace will slowly start spinning underneath the stands of Arizona Stadium at the University of Arizona. Fire-engine red, massive in size and resembling a sci-fi version of a Dutch oven, the furnace is the only one of its kind, and its sole purpose is to produce the world's biggest and most advanced telescope mirrors.
