Microbial miners could help humans colonize other planets • Earth.com

A new study led by the University of California, Irvine (UCI) has argued that the biochemical process by which cyanobacteria acquire nutrients from rocks in Chile's Atacama Desert could be employed in the future to build colonies on the moon and Mars.

By using high-resolution electron microscopy and advanced spectroscopic imaging techniques, the experts examined how microorganisms modify both naturally occurring minerals and synthetically made nanoceramics.

Viewing planets, moon in trip to desert - ARAB TIMES - KUWAIT NEWS

How hell planet covered in lava got so close to its star | Digital Trends

Of the over 5,000 known planets outside our solar system, one of the most dramatic is 55 Cancri e .

The planet orbits its star, 55 Cancri A, at a distance of 1.5 million miles which means a year there lasts less than a day here on Earth.

Researchers used a tool called the EXtreme PREcision Spectrometer (EXPRES) at the Lowell Observatory's Lowell Discovery Telescope in Arizona to look at the light coming from the host star and focused on the way that light changed when the planet moved between the star and Earth.

Skywatch: Holiday Mars madness – Twin Cities

It's been building since this past summer and culminates this month – the great Mars show of 2022. Even before evening twilight ends, Mars will be on the rise in the low eastern sky. It will certainly be the brightest star-like object in that part of the heavens, sporting an orange-red glow.

Mars and Earth are in what astronomers call opposition this week. That's when Earth lies in a line between the sun and Mars, putting Mars and Earth at minimum separation. It also makes Mars available all night long, rising at sunset and setting at sunrise.

The Sky This Week from December 9 to 16 | Astronomy.com

Friday, December 9
Jupiter's moons open this week with an alternating disappearing and reappearing act. Look southwest late this evening to find magnitude –2.5 Jupiter standing left (southeast) of the Circlet of Pisces. Zero in on the planet with a telescope and around 10 P.M.

But keep watching. Europa is inching closer to Jupiter's western limb. Just after 10:40 P.M. EST, Europa disappears behind the gas giant in an occultation. Not much later, shortly after 11 P.M.

Your guide to rings of the Solar System | The Planetary Society

Planetary rings come in all shapes and sizes. It only takes binoculars to spot Saturn's perfectly sculpted rings, but large telescopes or a space mission are needed to see the dim rings of Jupiter, Uranus, and Neptune.

All four of our Solar System's giant planets have rings. We've also found rings around asteroids, a dwarf planet, and a world orbiting another star. This guide will take you on a tour of our Solar System's marvelous halos and beyond.

The solar system can be broken down into three categories — the sun, Jupiter, and everything else. The sun is 1,000 times more massive than Jupiter, and Jupiter is two and a half times more massive than all of the other planets combined.
