Unveiling rogue planets with NASA's Roman Space Telescope
Aug 24, 2020 (SPX)
Astronomers discovered planets beyond our solar system, known as exoplanets, in the 1990s. We quickly went from knowing of only our own planetary system to real...
Mystery gas discovered near center of Milky Way
Aug 20, 2020 (SPX)
Exactly how the gas has been ejected is still a mystery, but the research team, including Professor Naomi McClure-Griffiths from The Australian National Univers...
Debris from Stellar Explosion Not Slowed After 400 Years
Aug 20, 2020 (SPX)
The Kepler supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. In 1604 early...
Strange gamma-ray heartbeat puzzles scientists
Aug 18, 2020 (SPX)
The research team, comprising scientists from Germany, Spain, China and the U.S., rigorously analysed more than ten years of data from the US space administrati...
Scientists use photons as threads to weave novel forms of matter
Aug 18, 2020 (SPX)
Positive and negative electric charges attract each other, forming atoms, molecules, and all that we usually refer as matter. However, negative charges repel ea...
Experiments replicate high densities in 'white dwarf' stars
Aug 18, 2020 (SPX)
In a project conducted at the National Ignition Facility at Lawrence Livermore National Laboratory, the research team, including University of Rochester enginee...
Arecibo Observatory data help lead to discovery of cosmic 'heartbeat'
Aug 18, 2020 (SPX)
The cloud is in the constellation Aquilla and "beats" in rhythm with a black hole 100 light years away in a microquasar system known as SS 433. The results were...
Webb Telescope is an international endeavor
Aug 14, 2020 (SPX)
Thousands of scientists, engineers, and technicians from 14 countries, 29 U.S. states, and Washington, D.C. contributed to build, test, and integrate Webb. In t...
Hubble finds that Betelgeuse's mysterious dimming is due to a traumatic outburst
Aug 14, 2020 (SPX)
Hubble researchers suggest that the dust cloud formed when superhot plasma unleashed from an upwelling of a large convection cell on the star's surface passed t...
NASA satellite's lone view of Betelgeuse reveals more strange behavior
Aug 14, 2020 (SPX)
Starting in late spring 2020, Betelgeuse has appeared close to the Sun in the sky because of Earth's position in space. However, the STEREO spacecraft is curren...
Astronomers discover most-distant Milky Way-like galaxy ever observed
Aug 12, 2020 (UPI)
When scientists study light from so far away, they're seeing something that is 12 billion years old, revealing the universe as it was just 1.4 billion years aft...
New study shows how the smallest galaxies produce stars
Aug 12, 2020 (UPI)
Dwarf galaxies don't typically host as many stars as larger galaxies like the Milky Way, but they're no lightweights either -- some have outsized stellar popula...
Miniature telescope demonstration focuses on sharpening view of distant objects in space
Aug 07, 2020 (SPX)
DeMi made first contact about a week following launch, demonstrating the expected power from its solar arrays, as well as correct spacecraft pointing and stable...
Astrophysicists Observe Long-Theorized Quantum Phenomena
Aug 03, 2020 (SPX)
This puzzling relationship between a white dwarf's mass and size - called the mass-radius relation - was first theorized by Nobel Prize-winning astrophysicist S...
Machine learning finds a surprising early galaxy
Aug 03, 2020 (SPX)
To understand galaxy evolution, astronomers need to study galaxies in various stages of formation and evolution. Most of the galaxies in the modern Universe are...
Astronomers find young galaxy with record-low oxygen levels
Aug 03, 2020 (UPI)
To find the tiny galaxy, researchers used machine learning algorithms to parse data collected by a pair of telescopes in Hawaii, the Subaru Telescope and W. M. ...
The stars that time forgot
Jul 30, 2020 (SPX)
The extraordinary discovery of this shredded 'globular cluster' is surprising, as the stars in this galactic archaeological find have much lower quantities of h...
Astronomers pinpoint the best place on Earth for a telescope: High on a frigid Antarctic plateau
Jul 30, 2020 (SPX)
"A telescope located at Dome A could out-perform a similar telescope located at any other astronomical site on the planet," said UBC astronomer Paul Hickson, a ...
Remnant of ancient globular cluster that's 'the last of its kind'
Jul 30, 2020 (SPX)
Imagine a sphere made up of a million stars bound by gravity and orbiting a galactic core. That's a globular cluster. The Milky Way is home to about 150 of them...
Studying radioactive aluminum in solar systems unlocks formation secrets
Jul 29, 2020 (SPX)
Because its radioactive decay is thought to provide a heat source for the building blocks of planets, called planetesimals, it's important for astronomers to kn...
