In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and...
NASA picks Starship to land on the moon because NASA is getting ready to send astronauts to explore more of the Moon as part of the Artemis program, and the agency has selected SpaceX to continue development of the first commercial...
A binary black holes is a pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light...
The "three-body problem," the term coined for predicting the motion of three gravitating bodies in space, is essential for understanding a variety of astrophysical processes as well as a large class of mechanical problems, and has occupied some of...
In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.
Data from 19 observatories...
Auroral displays continue to intrigue scientists, whether the bright lights shine over Earth or over another planet. The lights hold clues to the makeup of a planet's magnetic field and how that field operates.
New research about Jupiter proves that...
In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which...
The images capture drama billions of years ago in the early Universe—glinting galaxies, glowing with stars that have exploded into supernovas and blazing jets fired from black holes.
Europe's giant LOFAR radio telescope has detected stars being born in tens...
A group led by scientists from the RIKEN Cluster for Pioneering Research, using coordinated observations of the Crab pulsar in a number of frequencies, have discovered that the "giant radio pulses" which it emits include an increase in x-ray...
Every year, our planet encounters extraterrestrial dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some of them reach the ground in the form of micrometeorites. An international program...
One day, humankind may step foot on another habitable planet. That planet may look very different from Earth, but one thing will feel familiar -- the rain.
In a recent paper, Harvard researchers found that raindrops are remarkably similar across...
