If you find a big rock in your backyard, and you can’tbreak it open with normal tools, guess what?
The researchers argue that the Maryborough meteorite is much rarer than gold. It’s one of only 17 meteorites ever recorded in the Australian state of Victoria, and it’s the second largest chondritic mass, after a huge 55-kilogram specimen identified in 2003.
This next bit is more interesting to me:
“Other rare meteorites contain organic molecules such as amino acids; the building blocks of life.”
Do they have atmospheres and how thick are they? What kind of clouds? Do they possess oceans on their surface? Do they have rings and moons? Cheops ought to be able to address such questions just from looking for these tiny dips in light during a transit.
ESA finally does something! Wow. Go Europe!
I love how BBC says “The Americans” when referring to NASA, as if a) American is an ethnic group and b) all NASA scientists are American.
Prof Didier Queloz, who won this year’s Physics Nobel for discovering the first planet orbiting a Sun-like star in 1995, was on hand to watch the launch.
Future moon settlers might benefit from oxygen extraction from lunar regolith as it can be used to create breathable air as well as a source for fuel. In addition, the newly found extraction method might also be useful for Mars colonization.
Regolith covers the Moon and Mars (and presumably many other potentially habitable rocky bodies).
Of course, the composition of regolith on the Moon differs from that of Mars.
But if the new method can extract sufficient quantities of both oxygen and hydrogen, there should be ample amounts for both human usage and rocket fuel.
(Yawn.) “Dry” science? Sure. But think of the (fictional) possibilities!
We’ve learned a lot about Neptune’s largest moon, Triton, since it was first discovered in 1846. Some scientists believe it could be an “ocean world” with liquid water — and maybe even harbor life.
And now, pending approval, we might soon get our best glimpse yet. NASA’s Jet Propulsion Laboratory proposed on Tuesday [19 March 2019] at a conference in Texas to send a spacecraft called “Trident” to Triton — with the goal of sussing out whether it’s a habitable world.
A low-cost mission that would give us decent photos and even video of Triton, Io, and even Venus. Let’s do this.
Welp, it’s official. NASA announced they have confirmed another “Earth” (really, an “Earth-like planet” simply means it has enough water and is in the right orbit from its star to hypothetically support life).
Too bad it’s 500 light years away, which currently would take us a mere 70,000 years to reach.
