Alien Life: Notions and Research

Scientists have been discussing alien life for some time: where it could be, what it might be like, and how we could find it.

Quite a few non-scientists have been talking about the same thing.

Some have pretty good grip on what we've been learning since Aristotle got famous and Anaxagoras didn't.

Others have contributed to supermarket tabloid covers. And made informed discussion of extraterrestrial intelligence harder.

Or more interesting, depending on your viewpoint. I see it as a bit of both.

Still Seeking Earth 2.0

We've known about 55 Cancri e since 2004.

It may have lakes and rivers of lava. But that's probably not what keeps its night side hot enough to melt copper.

Ross 128 b, discovered this year, is a bit more massive than Earth, warm enough for liquid water, and too hot. It's not quite 'Earth 2.0,' but it may support life....

Visitor from the Stars

"Scientists thought ‘Oumuamua was a comet when they spotted it last month.

"Follow-up observations showed it was more like an asteroid: and going too fast to be from the solar system.

"‘Oumuamua is from interstellar space. It's the first object of its kind we've seen.

"What scientists are learning about ‘Oumuamua tells us a bit about other planetary systems, and raises intriguing new questions...."

Finding New Worlds

We could detect oxygen in Proxima Centauri b's atmosphere. It's a biosignature, but not proof of life.

Some extrasolar planets are like Earth, almost. Many are unlike anything in the Solar System.

I'll be looking at recently-discovered worlds; some almost familiar, others wonderfully unexpected. Also an informal 'top 10 best exoplanets' list.

Labor Day SETI

I nearly missed an interesting development in SETI, the Search for Extraterrestrial Intelligence. Interesting, and as newsworthy as most Stephen Hawking stories, but probably not significant.

Professor Hawking didn't start chatting with aliens over the Labor Day weekend. That would be major news.

But an outfit he's connected with will be listening to FRB 121102. I think it's likely that they'll collect useful data, and that this isn't a prelude to 'first contact.'

Other scientists say they've spotted several planets orbiting Tau Ceti. Two of them may be just inside that star's habitable zone.

New Worlds: The Search Continues

There's a huge telescope under construction in Chile: the E-ELT. When compete, astronomers using it plan plan on looking for new worlds, and observing the early universe.

We may have spotted a second super-Saturn. We'll know more about that in September....

...Telescopes have come a long way since Galileo repurposed the "Dutch perspective glass" for astronomical observation.

About Galileo, Copernicus, the sun, and the Church: it's true....

TRAPPIST-1: Water? Life??

TRAPPIST-1's planets may support life: or not. We don't know. Not yet.

We're pretty sure that all seven are rocky worlds, like the Solar System's inner planets.

Three are in the star's habitable zone. The inner two definitely do not have one sort of atmosphere that would make life as we know it impossible.

Even if we don't find life there, we'll learn a great deal while looking.

SETI: What If?

Contacting extraterrestrial intelligence, meeting people whose ancestors developed on another world, has been a staple of pulp fiction for generations.

Lately, it's become a matter for serious discussion. I'll be looking at an op-ed's take on how learning that we're not alone might affect folks with various religious beliefs. I'll also share what I expect: and what I don't....

Mars, Aliens, and SETI



I'd love to be talking about unambiguously artificial signals picked up by the Allen Telescope Array, or reports of a ship from beyond the Solar System settling into orbit around our moon.

But that hasn't happened, and probably won't. Not in my lifetime.

Instead, I'll talk about why I don't "believe in" extraterrestrial life; and do not assume that we are alone in the universe. That puts me in the third of folks who aren't sure, and I'll get back to that.

My 'Friday' posts are usually about more-or-less-current 'science news.' That won't happen this week. I've read a few interesting articles, and will be talking about them — after the Christmas-New Year's gymkhana is over.

This week I'm using material that didn't quite fit into an earlier post. I'll also talk about the Great Moon Hoax, Nicola Tesla and Martians; and what I think about life in the universe.
