University Deletes Press Release Claiming Evidence of Bugs on Mars

Posted by in category: space

“I, personally, have pareidolia with respect to insects, beetles in particular,” Maddison told Space.com. “I’ve worked on beetles for decades; I have collected many thousands of beetles around the world. Through the years I have built into my brain a pattern-recognition system for picking out beetles.”

In other words, Rosomer is probably wrong, even though he probably thinks he’s right.

“I do not think there are insects on Mars,” Maddison added. “The photographs that are in that press release you sent are entirely unconvincing, as they fall within the range expected in zillions of non-insect objects photographed in lowish resolution on a Marscape.”

Scientists Found Breathable Oxygen in Another Galaxy for the First Time

Posted by in category: space

Molecular oxygen is a key component of the air humans breathe, and now astronomers have spotted it a half-billion light years away. But don’t hold your breath for quasar whippets.

Scientists discover BREATHABLE OXYGEN in a galaxy outside of the Milky Way for the first time — the only problem is it’s 581 million light years away

The discovery was made by a team of astronomers at Shanghai Astronomical Observatory, led by Junzhi Wang.

The team identified the presence of molecular oxygen by analyzing light waves that had reached Earth from Markarian 231, a galaxy around 581 million light years away.

Japan will launch the first-ever sample return mission from the Martian system

Posted by in categories: mapping, robotics/AI, space

JAXA, Japan’s national space agency, has just approved a robotic mission to visit the Martian moons Phobos and Deimos and retrieve a small sample from the former to bring back to Earth.

The mission plan: It’s called Martian Moon eXploration, or MMX. JAXA currently plans to launch MMX in 2024 and make it to the Martian system the following year. MMX will spend three years in the system studying and mapping the moons. The mission will make use of 11 different instruments, including a NASA-funded instrument called MEGAE that will measure the elemental composition of both bodies (perhaps revealing signs of ancient water).

The mission will also deploy a small rover to zip around the surface of Phobos, not unlike what JAXA’s Hayabusa2 mission deployed on the surface of the asteroid Ryugu.

Jupiter-like exoplanet orbits its star in only 18 hours

Posted by in category: space

Astronomers have observed an exoplanet orbiting a star in just over 18 hours – the shortest orbital period ever seen for a planet of its type.

This means that a single year for this hot Jupiter-like planet – a gas giant similar in size and composition to Jupiter in our own Solar System – passes in less than a day of Earth time.

Scientists believe the discovery may help solve the mystery of whether such planets are in the process of spiralling towards their suns to their destruction.

The New Horizons spacecraft just revealed secrets of the most distant object we’ve ever visited

Posted by in categories: computing, space

Now, five years later, their gamble appears to have paid off. Not only did New Horizons achieve a next-to flawless flyby of Arrokoth, the most distant object ever visited, but buried in its gigabytes of data—which have been trickling back to Earth ever since the New Year’s Day 2019 rendezvous—lies empirical evidence that strikes against a classic theory of how planets form. The New Horizons team published their latest analysis of the ancient body and how it came to be in a trio of papers appearing in Science last week.
