Through the centuries, scientists and non-scientists alike have looked at the night sky and felt excitement, intrigue, and overwhelming mystery while pondering questions about how our universe came to be, and how humanity developed and thrived in this exact place and time. Early astronomers painstakingly studied stars' subtle movements in the night sky to try and determine how our planet moves i 'Old Faithful' cosmic eruption shows black hole ripping at star
Write a comment
You've heard of Old Faithful, the Yellowstone National Park geyser that erupts every hour or two, a geological phenomenon on a nearly predictable schedule.
Now, an international group of scientists who study space have discovered an astronomical "Old Faithful" - an eruption of light flashing about once every 114 days on a nearly predictable schedule. The researchers believe it is a tidal d The earliest supermassive black hole and quasar in the universe

The most distant quasar known has been discovered. The quasar, seen just 670 million years after the Big Bang, is 1000 times more luminous than the Milky Way, and is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of the Sun.
Seen more than 13 billion years ago, this fully formed distant quasar is also the earliest yet discover Defense, Commerce departments join to find 5G solutions

The U.S. departments of Defense and Commerce will jointly seek public input on development of 5G communication networks, they announced on Monday.
5G, or fifth generation telecommunications standard for broadband cellular networks, offers higher download speeds and has been of particular interest to the U.S. military prior to its civilian rollout in 2019.

Linear accelerators, LINACs for short, are devices that accelerate electrons or other sub-atomic particles along a straight line to generate a beam of high energy. LINACs have a variety of commercial uses such as generating X-rays for cargo inspection, medical diagnostics, food sterilization, and even enabling precise external radiation treatments to destroy cancer cells without damaging surroun Cultivating plant growth in space

When in space, astronauts typically eat dehydrated, nutrient-dense food, but when it comes to longer space missions, that can become a problem as they'll eventually lack nutrients from fresh vegetables. However, one chemical and biomolecular engineering professor will be researching ways astronauts can grow their own fresh vegetables more efficiently while they are on missions.
Ying Diao w Astronomers finally measure polarized light from exoplanet
Write a comment
An international team led by Dutch astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarized light from an exoplanet. They can deduct from the light that a disk of dust and gas is orbiting around the exoplanet in which moons are possibly forming. The researchers will soon publish their findings in the journal Astronomy and Director General’s annual press conference 2021

A robot made of ice could adapt and repair itself on other worlds
Write a comment
Some of the most tantalizing targets in space exploration are frozen ice worlds. Take Jupiter's moon Europa, for instance. Its warm, salty subsurface ocean is buried under a moon-wide sheet of ice. What's the best way to explore it?
Maybe an ice robot could play a role.
Though the world's space agencies—especially NASA—are getting better and better at building robots to explore places like Mars, those robots have limitations. Perhaps chief among those limitations is the possibility of breakdown. Once a rover on Mars—or somewhere even more distant—breaks down, it's game over. There's no feasible way to repair something like MSL Curiosity if it breaks down while exploring the Martian surface.
But what if the world being explored was a frozen one, and the robot was made of ice? Could icy robots perform self-repair, even in a limited fashion? Could they actually be manufactured and assembled there, even partly?

Prepping for a spacewalk typically means diving underwater to rehearse and fine-tune operations.
In 2016, ESA astronaut Alexander Gerst performed such an underwater rehearsal for the ColKa high speed radio, the brown box imaged above, that will be installed this month on the International Space Station.
NASA astronauts Mike Hopkins and Victor Glover will integrate the small fridge-sized device outside the European Columbus module during a spacewalk scheduled this year. ESA astronaut Andreas Mogensen will be at NASA's mission control directing the spacewalkers as Capcom. The Columbus Ka-band terminal, nicknamed "ColKa," will enable faster communication with Europe.
Orbiting the planet every 90 minutes means the Space Station is constantly making and breaking short links with ground stations on Earth as it passes over them at a height of 400 km.
With Colka, a European telecommunications satellite in geostationary orbit can pick up data sent from the Columbus module. This satellite is part of the European Data Relay System and will be able to directly relay the signals from Columbus to European soil via a ground station in Harwell, in the U.K.
