Big asteroids hit Earth more frequently than thought, study suggests
Four big asteroids hit Earth in the past million years alone, according to a new study, suggesting that the space-rock danger is higher than previously thought. But not everyone agrees with the result.
DART mission reveals asteroid Dimorphos is dry as a bone
Careful scrutiny of the debris from the impact of NASA's DART mission into Dimorphos has not found any evidence for water ice on the asteroid, nor the residue of thruster fuel from the spacecraft.
Private Japanese moon lander reaches lunar orbit
The Hakuto-R moon lander entered lunar orbit late Monday night (March 20), notching a huge milestone for the Japanese company ispace and private spaceflight in general.
Building block of life found in sample from asteroid Ryugu
An organic compound that's part of the RNA molecules that transmit genetic information in cells has been discovered in samples from the asteroid Ryugu, suggesting the stuff of life came from space.
Facts about Neptune
Neptune is the eighth and farthest known planet from the Sun in the Solar System. Here are some interesting facts about Neptune:
- Neptune is the fourth largest planet in the Solar System, with a diameter of about 49,244 km (30,598 miles).
- It was named after the Roman god of the sea, Neptune.
- Neptune has the strongest winds in the Solar System, with speeds that can reach up to 2,100 kilometers per hour (1,300 miles per hour).
- It takes Neptune about 164.8 Earth years to complete one orbit around the Sun.
- Neptune is the coldest planet in the Solar System, with temperatures that can drop as low as -220 degrees Celsius (-364 degrees Fahrenheit).
- Neptune has 14 known moons, the largest of which is Triton. Triton is one of the coldest known objects in the Solar System, with a surface temperature of about -235 degrees Celsius (-391 degrees Fahrenheit).
- Neptune’s atmosphere is primarily composed of hydrogen, helium, and methane gas, which gives the planet its blue color.
- Neptune was first discovered in 1846 by the French mathematician Urbain Le Verrier, based on mathematical calculations of irregularities in the orbit of Uranus.
- The Voyager 2 spacecraft is the only spacecraft to have flown by Neptune, in 1989. It provided the most detailed information about the planet and its moons.
- Neptune’s magnetic field is tilted at an angle of about 47 degrees to its rotational axis, which is one of the most extreme tilts among the planets in the Solar System.
Watch Jupiter meet the moon and Mercury this week before leaving the night sky
Jupiter will meet up with the moon before joining Mercury in late March, after which it will disappear in the glare of the sun until it reappears in May.
Amateur astronomers needed: help classify stars with Gaia's data
ESA's Gaia mission has been collecting data on millions of space objects like stars and asteroids to build an extensive cosmic record. Now, to take it up a notch, it needs your eyes.
Machine Learning Finds 140,000 Future Star Forming Regions in the Milky Way
Our galaxy is still actively making stars. We’ve known that for a while, but sometimes it’s hard to understand the true scale in astronomical terms. A team from Japan is trying to help with that by using a novel machine-learning technique to identify soon-to-be star-forming regions spread throughout the Milky Way. They found 140,000 of them.
If Titan Has the Chemistry For Life, Dragonfly Could Find it
The highly-anticipated Dragonfly robotic rotocraft mission to Saturn’s moon Titan is scheduled to launch in 2027. When it arrives in the mid-2030s, it will hover and zoom around in the thick atmosphere of Titan, sampling the air and imaging the landscape. What could be more exciting than that!?
Mysterious radio signal reveals intricate core of distant galaxy cluster
Astronomers have discovered several fascinating features in galaxy cluster Abell 1213 such as a central galaxy with a 1.66 million light-year-long radio "tail" and remains of galactic mergers.
Spot dwarf planet Ceres during the new moon tonight (March 21)
The dark skies of the new moon will offer skywatchers the chance to spot Ceres tonight (March 21), as the dwarf planet reaches opposition.

Rocket Lab plans to launch two satellites early Wednesday morning (March 22), on a mission that includes a booster recovery at sea. Watch it live here.
This Galaxy Is Powerful, But Lonely Too
A large elliptical galaxy spewing a black hole–powered jet might have eaten its neighbors, leaving it on its own.
Astronauts that hibernate on long spaceflights is not just for sci-fi. We could test it in 10 years.
First hibernation studies with human subjects could be feasible within a decade, a European Space Agency (ESA) researcher thinks.
Watch solar tornado as tall as 14 Earths hurl plasma cloud into space (video)
NASA's Solar Dynamics Observatory captured what might be 'the tallest tornado' in the solar system swirling across the north pole of the sun.

Asteroid Analysis Reveals Prebiotic Compounds
Prebiotic compounds previously found in meteorites have now turned up in pristine samples from the asteroid Ryugu, confirming their extraterrestrial origin.
JWST Sees Organic Molecules Swirling Around a Newborn Star
One of the most interesting questions we can ask is, “How did life form?”. To answer it, scientists go back to look at the basic chemical building blocks of life. Those are water, carbon-based organic molecules, silicates, and others. The James Webb Space Telescope offered a peek at the gases, ice particles, and dust surrounding a newborn star and found organic molecules exist there.
The Favorite Solar System Moons of Planetary Geologists; An In-Depth Discussion
The moons of our Solar System have garnered quite a lot of attention in the last few years, especially pertaining to astrobiology and the search for life beyond Earth. From the Galilean moons of Jupiter to the geysers of Enceladus to the methane lakes on Titan, these small worlds continue to humble us with both their awe and mystery. But do the very same scientists who study these mysterious and intriguing worlds have their own favorite moons? As it turns out, seven such planetary geologists were kind enough to share their favorite Solar System moons with Universe Today!
