Science NASA News Conference - More Exoplanets

[Shaboid]

NASA is holding a news conference at 10 a.m. Pacific Time on Wednesday, Feb. 22, to present new findings on planets that orbit stars other than our sun, known as exoplanets. You can view it here on NASA's website: https://www.nasa.gov/multimedia/nasatv/index.html#public Tune in then!

Nearby Star Has 7 Earth-Sized Worlds

The individuals attending this press event at NASA have been looking for planets circling other stars. Last year one of the participants, Michael Gillon, was lead author on a paper "Temperate Earth-sized planets transiting a nearby ultracool dwarf star" in Nature detailing how his team had confirmed 3 small terrestrial (Earth-sized) planets circulating a cool dwarf star 2MASS J23062928-0502285 (now known as TRAPPIST-1), a M8V class star which is only 39.5 light years away.

It will be announced tomorrow by NASA that Gillon et al have confirmed 4 more Earth-sized planets circling TRAPPIST-1. It is possible that most of the planets confirmed thus circling far TRAPPIST-1 could be in the star's habitable zone. The inner 6 planets are probably rocky in composition and may be just the right temperature for liquid water to exist (between 0 - 100 degrees C) - if they have any water, that is. The outermost 7th planet still needs some more observations to nail down its orbit and composition.

Dr. Riess and his colleagues have stood by their work, however, and the plot thickened further in December when a group called H0LiCOW (don’t ask) from the Max Planck Institute for Astrophysics in Garching, Germany, reported its own value of 72 for the Hubble constant, also inconsistent with the Planck space mission’s analysis.

That got a chuckle out of me. Leave it to the freaking Germans.

Just started!

So there is a star called Trappist-1, with 7 earth sized planets, of which three in the "habitable zone". This system is 40 light years away from Earth.

I'm glad the leak I found last night was actually right about their announcement.

alt planets.....awesome findings..!

are all those planets flat too?

 

[Shaboid]

Pretty cool they are making that data available so quickly.

That is fucking insane. That entire Q&A was awesome.

BTW, watch The Expanse. Great sci fi show.

I heat the press cinference on one of the exoplanets was pretty relavatory as well. Now go find the Dark Obelisk guys.

We'll be doing our best to send you Mathew McConaughey before we nuke ourselves back to where your current evolutionary level is.

AM Joy every Saturday asks the question "who won the week?"
I'll vote for Trappist-I.

No headline developments above, but hopefully the continued JWST research can provide valuable insight.

Is this a hint of life on another world, or just a lot of hot air?

In this case, the purportedly tell-tale gases that appear to be in this planet's atmosphere are either dimethyl sulfide, dimethyl disulfide, or some combination of the two. On Earth, these are only produced by life, particularly by marine microbes.

So the other world is just farty, eh?
