“Being able to get humans on Mars and actually collecting one of these samples would be such an incredible moment, I would kind of hope it would almost bring us back to the moon days of everyone being glued to the TV.”
Um. Well. OK. TV is dead so we’ll all be watching it streamed on our smartphones, but the point is taken.
“Proxima is our closest neighbor in an immense universe. How could we not be charmed by it?”
Well, the planet may or may not exist (the confirmation data won’t be publicly available for another couple years).
And it is most likely not inhabitable — despite being dubbed a “Super-Earth” (which really only refers to size and not whether it’s “Earth-like” or not).
“We tried different tools to prove ourselves wrong, but we failed. However, we have to keep the doors open to all possible doubt and skepticism.”
Yes, the astronomers tried to prove their own discovery was a mistake. That’s how it works, folks. Challenge your assumptions, not jump to conclusions. Continue Reading
Are you sitting down for this? Well, you’re not really. Your butt isn’t actually touching the chair you’re sitting on. Since the meat of your atoms is nestled away in nuclei, when you ‘touch’ someone (or something), you aren’t actually feeling their atoms.
“Without this instability, Mars likely would have had a mass closer to Earth’s and would be a very different, perhaps more Earth-like, planet compared to what it is today.”
Damn you, Jupiter and Saturn! Why couldn’t you have just stayed in your orbits and left Mars alone? (Shakes fist futilely at night sky.)
The newly discovered exoplanet, called TOI 700 d, is located about 100 light-years away from us and is roughly 20% larger than Earth.
Okay, not exactly close, but looking good…
A year on TOI 700 d takes 37 days.
Um. Wait. What?
One thing astronomers have discovered though is that TOI 700 d is tidally locked to its star, which means that one half bathes in eternal sunlight, and the other half always exists in darkness.
Oy.
And even better…
One of the burning questions is whether the planet has an atmosphere or not.
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.
But anyway…
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.
