NASA finds ancient lava flows deep below Mars’ surface

Before the NASA InSight lander plunged through Mars’ atmosphere and parachuted its way down to the planet’s surface, scientists were already pretty familiar with the surface of Mars, but not what was on the inside. “We’ve got 15 years of information about the surface, we’ve measured the topography, the atmosphere, the magnetic field — but … Read more

What place for women in ancient Rome?

1st century sculptures from the Roman garden of Gaius Cilnius Maecenas, friend and political adviser to Octavian. CAPITOLINE MUSEUMS / FLICKR The exhibition. Carrying a pejorative charge in French to the point of sometimes qualifying a patroness as a brothel, the word “matron” in ancient Rome, on the contrary, designated the model wife and mother. … Read more

Ethical debates on the study of ancient human DNA

Paleontology. Only twelve years ago, no complete genome of ancient humans was available. Today, there are more than 6,000 of them. This revolution in paleogenomics has completely changed the study of our distant past, of interbreeding with our deceased cousins, of migrations and populations, but also of the physiological specificities of certain current populations. – … Read more

Perseverance rover finds evidence of ancient floods on Mars, researchers say

The Perseverance rover, which spent months traveling to Mars, could hardly have landed in a more interesting spot. The Jezero crater — a dry, wind-scoured patch of Martian rock where the rover touched down in February — was once a lake bed fed by an ancient river with floods so powerful they could move boulders, … Read more

First images from latest Mars rover show ancient river delta in Jezero crater | Imperial News

The NASA Perseverance rover, which landed on Mars in February, has sent back its first images of a 3.7-billion-year-old ancient river delta. The images reveal that the watery life cycle of the now dried-out lake at Jezero Crater – the site of Perseverance’s touchdown – is more intriguing and complicated than originally thought. The pictures … Read more

Perseverance rover confirms existence of ancient Mars lake and river delta

NASA chose the landing site of its life-hunting Perseverance Mars rover wisely. Perseverance touched down in February on the floor of the 28-mile-wide (45 kilometers) Jezero Crater, which was picked primarily because previous observations by Mars orbiters suggested that it hosted a big lake and a river delta in the ancient past. Photos snapped by … Read more

“Once-in-a-lifetime” tardigrade found in ancient amber

Microscopic eight-legged invertebrates that resemble squishy bears are among the toughest creatures on Earth, with the ability to survive decades without food, extreme temperatures and even in the vacuum of space. Fossils of the creatures are extremely rare, with only two being found in history — until now. In a new study published on Wednesday, … Read more

NASA Announces a Dark, Eerie Moon Landing Site For Its Next Rover Mission

NASA is embarking on a new Moon shot, aiming to one day build a permanent crewed station on the lunar surface. Before it sends any people, though, the agency is launching a golf-cart-sized robot to the Moon’s freezing, shadowy south pole. The rover, called the Volatiles Investigating Polar Exploration Rover (VIPER), will spend 100 days … Read more

Ancient Mars was once home to thousands of supervolcanoes

Mars is a relatively quiet and uneventful place today, but topographical evidence suggests the planet had a violent past. A recent NASA study found that the Arabia Terra region of northern Mars was once home to thousands of massively explosive supervolcanoes, which produce the biggest eruptions known to science. Earth is home to a handful … Read more

NASA confirms Mars region had thousands of ancient volcanic eruptions

NASA scientists have found evidence that thousands of massive ancient volcanoes erupted on Mars. The so-called “super eruptions” occurred in a region of northern Mars called Arabia Terra over a period of 500 million years dating back approximately 4 billion years. NASA’S PERSEVERANCE ROVER TEAM DRILLS FIRST MARTIAN ROCK SAMPLE Researchers who studied the topography … Read more
