Dark Coating Can Reduce Satellite Reflectivity

Observations confirmed that dark coating can reduce satellite reflectivity by half. There are concerns that numerous artificial satellites in orbit could impair astronomical observations, but these ...

The missing dark matter in certain galaxies can be explained by the effects of tidal disruption: the gravity forces of a neighboring massive galaxy, literally tearing the smaller galaxy ...

Earth Faster, Closer to Black Hole, in New Map of Galaxy

Earth 'just got' 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy. But don't worry, this doesn't mean that our ...

Astronomical Instrument Hunts for Ancient Metal

Researchers created a new astronomical instrument that has successfully aided in estimating the abundance of metals in the early universe. The WINERED instrument allows for better observations of ...

Puzzling 'Cold Quasar' Forming New Stars in Spite of Active Galactic Nucleus

Using NASA's SOFIA telescope, researchers have found CQ 4479, a galaxy which never had been closely studied before, to be generating new stars in spite of a luminous AGN at the galaxy's ...

New Insights on Health Effects of Long-Duration Space Flight

Among the new findings, the research team found that chronic oxidative stress during spaceflight contributed to the telomere elongation they observed. They also found that astronauts had shorter ...

Space Travel Can Adversely Impact Energy Production in a Cell

Studies of both mice and humans who have traveled into space reveal that critical parts of a cell's energy production machinery, the mitochondria, can be made dysfunctional due to changes in ...

Growing Interest in Moon Resources Could Cause Tension

An international team of scientists has identified a problem with the growing interest in extractable resources on the moon: there aren't enough of them to go around. With no international ...

Scientists Make Sound-Waves from a Quantum Vacuum at the Black Hole Laboratory

Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behaviour of black ...

Floods of unimaginable magnitude once washed through Gale Crater on Mars' equator around 4 billion years ago -- a finding that hints at the possibility that life may have existed there, ...

Blue Ring Nebula: 16-Year-Old Cosmic Mystery Solved, Revealing Stellar Missing Link

Astronomers have solved the 16-year-old mystery surrounding the Blue Ring Nebula - an unusual, large, faint blob of gas with a star at its center. This object is unlike any they'd ever seen ...

Ancient Zircon Minerals from Mars Reveal the Elusive Internal Structure of the Red Planet

Analysis of an ancient meteorite from Mars suggests that the mineral zircon may be abundant on the surface of the red planet. By determining the age and hafnium isotope composition of these zircons, ...

Cosmic Flashes Come in All Different Sizes

By studying the site of a spectacular stellar explosion seen in April 2020, scientists have used four European radio telescopes to confirm that astronomy's most exciting puzzle is about to be ...

Building Blocks of Life Can Form Long Before Stars

An international team of scientists have shown that glycine, the simplest amino acid and an important building block of life, can form under the harsh conditions that govern chemistry in ...

Scientists Expand Space Instrument's Capabilities

Scientists have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX ...

An international crew of astronauts is en route to the International Space Station following a successful launch on the first NASA-certified commercial human spacecraft system in history. NASA's ...

Aurora-Chasing Citizen Scientists Help Discover a New Feature of STEVE

A new finding about the formation of streaks within the aurora-like STEVE phenomenon brings scientists one step closer to solving the ...

History of Temperature Changes in the Universe Revealed
