Astrobiologists Detect a Signature of Life on Mars

When light shines on biological matter, part of the wavelength of the light that is reflected back is curled in either a clockwise or counterclockwise spiral. Astrobiologists used this phenomena in their remote sensing technique.

Mars Helicopter Succeeds in Historic First Flight

Monday, NASA's Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The flight was a success.

First X-rays from Uranus discovered

Astronomers have detected X-rays from Uranus using NASA's Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our solar system.

First audio recordings from Mars Perseverance rover

NASA’s Perseverance Rover that landed on Mars last month has beamed back historic audio recorded on the surface of the Red Planet.

China′s Tianwen-1 enters Mars orbit

A day after the UAE's Hope probe entered into the orbit of Mars, China has followed suit. In May, the probe will land a Chinese rover on Mars. The goal of Tianwen-1 is to survey the atmosphere from orbit.

NASA rover reaches Mars in search for signs of past life

Perseverance, the largest, most advanced rover NASA has sent to another world, touched down on Mars yesterday. The $2.4 billion rover arrived at Jezero Crater, a basin that scientists say was once flooded with liquid water.

'Signs of life' on Venus might just be ordinary sulfur gas

The widely-publicized detection of phosphine gas on Venus – a possible "biosignature" suggesting the hellish planet could have living microbes in its clouds – was probably caused by sulfur gas.

NASA InSight Lander's Mole Is No Longer Digging Mars

Since 2019, NASA's InSight's probe, called the “mole,” has been attempting to burrow into the Martian surface. Martian soil’s tendency to clump deprived the mole of the friction it needs to hammer itself to a sufficient depth.

Saturn's tilt caused by its moons

The current tilt of Saturn's rotation axis is caused by the migration of its satellites, and especially by that of its largest moon, Titan. Titan and the other moons are moving away from Saturn much faster than it had been previously estimated.

A Map of Mars' Entire Ancient River Systems

Three to four billion years ago, Mars did in fact have running rivers of water. Now, scientists have mapped out an entire ancient river system.

Dark storm on Neptune reverses direction

Astronomers using NASA's Hubble Space Telescope watched a mysterious dark vortex on Neptune (a storm, which is wider than the Atlantic Ocean) abruptly steer away from a likely death on the giant blue planet.

Where were Jupiter and Saturn born?

New work reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the Solar System's unusual architecture, including the ejection of an additional planet between Saturn and Uranus.

Venus' Atmosphere Contains Amino Acids

A team of researchers claims they've discovered the amino acid glycine in Venus' atmosphere. There are about 500 known amino acids, but only 20 are present in the genetic code. Glycine is the simplest of them.

Possible Microbial Life on Venus

An international team of scientists have recently found the abundances of phosphine in the Venusian cloud decks. It might - just might - be a biosignature.

Jupiter Probably Has 600 Small, Irregular Moons

In recent years, the confirmed number of Jovian moons has risen to 79. Now, a new study says that there may be 600 small irregular moons orbiting Jupiter.
