‘Ted Lasso’ Star Jason Sudeikis Talks Mental Health At White House
The stars of Apple TV+’s “Ted Lasso” appeared at the White House on Monday to discuss the importance of mental health. “No matter who you are, no matter where you live, no matter who you voted for,” we all know someone who has “struggled, that’s felt isolated, that’s felt anxious, that has felt alone,” said […]
An ocean of galaxies awaits: New COMAP radio survey will peer beneath the ‘tip of the iceberg’ of galaxies to unveil a hidden era of star formation
Sometime around 400 million years after the birth of our universe, the first stars began to form. The universe’s so-called dark ages came to an end and a new light-filled era began. More and more galaxies began to take shape and served as factories for churning out new stars, a process that reached a peak […]
Citizen scientist leads discovery of 34 ultracool dwarf binaries
How often do stars live alone? For brown dwarfs — objects that straddle the boundary between the most massive planets and the smallest stars — astronomers need to uncover more examples of their companions to find out. Ace citizen scientist Frank Kiwy has done just that by using the Astro Data Lab science platform at […]
Physicists embark on a hunt for a long-sought quantum glow: A new approach could make it possible detect the elusive Unruh effect in hours, rather than billions of years.
For “Star Wars” fans, the streaking stars seen from the cockpit of the Millennium Falcon as it jumps to hyperspace is a canonical image. But what would a pilot actually see if she could accelerate in an instant through the vacuum of space? According to a prediction known as the Unruh effect, she would more […]
Even dying stars can still give birth to planets
Planets are usually not much older than the stars around which they revolve. Take the Sun: it was born 4.6 billion years ago, and not long after that, Earth came into the world. But KU Leuven astronomers have discovered that a completely different scenario is also possible. Even if they are near death, some types […]
Sidewinding young stellar jets spied by Gemini South: Crystal-clear images of meandering bipolar stellar jets from young stars captured with adaptive optics
Sinuous stellar jets meander lazily across a field of stars in new images captured from Chile by the international Gemini Observatory, a Program of NSF’s NOIRLab. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars. These crystal-clear observations […]
Astronomers explain origin of elusive ultradiffuse galaxies: How very faint dwarf galaxies are born
As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions about UDGs remain unanswered: How did these dwarfs end up so extended? Are their dark matter halos — the halos of […]
Hydrogen-burning white dwarfs enjoy slow aging
The prevalent view of white dwarfs as inert, slowly cooling stars has been challenged by observations from the NASA/ESA Hubble Space Telescope. An international group of astronomers have discovered the first evidence that white dwarfs can slow down their rate of ageing by burning hydrogen on their surface. “We have found the first observational evidence […]
Scientists detect characteristics of the birth of a major challenge to harvesting fusion energy on Earth
A key challenge for scientists striving to produce on Earth the fusion energy that powers the sun and stars is preventing what are called runaway electrons, particles unleashed in disrupted fusion experiments that can bore holes in tokamaks, the doughnut-shaped machines that house the experiments. Scientists led by researchers at the U.S. Department of Energy’s […]
