What do redshifts tell astronomers?
A redshift reveals how an object is moving in space and enables astronomers to discover otherwise-invisible planets and the movements of galaxies, and to uncover the beginnings of our universe. Source: https://earthsky.org/astronomy-essentials/what-is-a-redshift…
James Webb Space Telescope passes environmental testing
The James Webb Space Telescope – successor to the Hubble – just passed a series of environmental testing trials, designed to simulate the rigors of its anticipated launch in 2021. Source: https://earthsky.org/space/james-webb-space-telescope-passes-environmental-testing…
James Webb Space Telescope launch date delayed
NASA is delaying the launch of the James Webb Space Telescope for another 7 months, from March 2021 to October 31, 2021 due to, among other factors, work stoppages during the coronavirus pandemic. Source: https://earthsky.org/space/james-webb-space-telescope-launch-date-delayed-oct2021…
A monster quasar in the early universe
Astronomers just announced the most massive quasar yet known in the early universe. Its monster central black hole has a mass equivalent to 1.5 billion of our suns. The object has been given a Hawaiian name, Poniua’ena. Source: https://earthsky.org/space/poniuaena-monster-quasar-in-early-universe…
New Exotica Catalog will help guide search for ET
“What if extraterrestrial intelligences are not like us, but are found in the frigid reaches of the outer solar system, the extreme gravity of neutron stars, the brilliant cores of active galaxies, or the hearts of the richest galaxy clusters?” Source: https://earthsky.org/space/the-breakthrough-listen-exotic-target-catalog-seti-extraterrestrial-intelligence…
Hubble makes surprising find in the early universe
New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought. A European team of astronomers have found no evidence of the first generation of stars, known as Population III stars, as far back as when the Universe was just 500 million years old. Source:…
Charting a course toward quantum simulations of nuclear physics
In nuclear physics, like much of science, detailed theories alone aren’t always enough to unlock solid predictions. There are often too many pieces, interacting in complex ways, for researchers to follow the logic of a theory through to its end. It’s one reason there are still so many mysteries in nature, including how the universe’s basic building blocks coalesce and form…
Black Hole Photo May Also Have Captured Light From Around the Universe
“When you point a telescope at a black hole, it turns out you don’t just see the swirling sizzling doughnut of doom formed by matter falling in,” reports the New York Times. “You can also see the whole universe.” Light from an infinite array of distant stars and galaxies can wrap around the black hole like ribbons around a maypole, again…
