Interesting article with a good summary of the state of AI today, and its prospects for the future.

Amazing news from Voyager 1, humanity's furthest envoy ever.

VLT: 'Oumuamua: more like a red stick than a grey potato.

Continuing observations on 'Oumuamua by ESO's Very Large Telescope in Cerro Paranal have determined that it's about 10 times longer than thick, and that, despite being made of stone, it's red in color due to being covered in red organic compounds.

This looks like a monster from the depths... Which I guess it is (Jupiter picture taken by the Juno probe, source: https://astronomynow.com/2017/11/19/jovian-tempest/)

Periodic Table of Exoplanets

Great visualization aid to help us understand the distribution of exoplanets found so far.

Notice that most of them are "hot" (is, orbit close to their star). The article doesn't mention it, but IMHO this is very likely an artifact of our current detection technologies: we basically detect exoplanets when they "transit", ie pass in front of their star on the line-of-sight from us. And it's much more probable to detect transits for planets close to their stars, due to more frequent transits (the planet orbits their stars faster).

Ross 128B is the closest exo-Earth planet found so far, and due to its star's proper motion, it's getting closer by the minute.

All hail  'Oumuamua, and may we track it long and good.

This is an update of my previous post regarding the first detected interstellar visitor to the Solar System, here: https://plus.google.com/+DurvalMenezes/posts/hzGNCnR9TsU

This article linked below nicely documents not only its naming, but also what we've learned of this object since then.

The success story of fighting the ozone depletion via the reduction in emission of harmful gases shows that Humanity can reverse the flow of destruction on Nature, if there's leadership and commitment between Nations.

Unfortunately I don't see this happening for Climate Change (eg, carbon emissions) anytime soon... And it may be already too late to avoid its worst effects.

Very interesting article. Due to its orbit, a recently detected comet has probably originated from another star. EDIT: the object had been named 'Oumuamua as is no longer considered cometary but rather of asteroidal nature, see my follow-up post here: https://plus.google.com/+DurvalMenezes/posts/8TiAD6UxbAe

The article doesn't mention it, but I think this could give a boost to the panspermia hypothesis (that life itself originated from outside the solar system and was brought to Earth by a comet or asteroid).

Wait while more posts are being loaded
