Earth-Sized Planet Orbiting Proxima Centauri b.

From The Daily Galaxy today, 28/5/20.

Proxima Centauri b is of course the nearest star to our own sun. The planet – discovered via an update to the HARPS method of plabnet detection known as ESPRESSO – is 1.17 times the size of Earth and orbits its star in 11.2 Earth Days and would be in the habitable zone if the star didn’t deluge it in X-rays. If the planet has an atmosphere though, those might be absorbed.

Birth of a Planet

From The Daily Galaxy for 20/5/20.

The kink in bright yellow may be where a planet is forming. That we as a species can observe such things is mind-boggling.

The Origins of Language

Via The Daily Galaxy I navigated to this interesting article arguing that neither our species, Homo Sapiens, nor indeed its sometime companion on the planet, Homo Neanderthalensis (which was not, as commonly believed, wiped out by us but subsumed, since Neanderthal DNA forms part of the modern human genome,) invented language. Rather, a predecessor of both species, Homo Erectus, deserves that accolade.

Fly Through Orion

Courtesy of The Daily Galaxy (and the Hubble Telescope) plus some technological trickery here is a visual fly-through of the Orion Nebula in visible and infra-red light.


Surface of Antares

Antares, the dying supergiant.

This is the surface of another sun!

Fly Over Pluto and Charon

Videos made from actual New Horizons footage and digital models of the surfaces of Pluto and Charon are now on You Tube. (I got the steer from the Daily Galaxy.)

Mathematical Time Travel

According to this post from The Daily Galaxy, time travel is mathematically possible.

Not by a time machine as such but in “a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path.”

Ben Tippett from the University of British Columbia has created a formula that describes the method. Unfortunately that formula the does not figure in the post. The method also requires bending of space-time by exotic matter – which hasn’t been discovered yet/ Might as well be Science Fiction.

The bubble is described as a Traversable Acausal Retrograde Domain in Space-time. The acronym spells TARDIS. Ha very ha.

EM-Drive?

This peer reviewed paper seems to be experimental proof of an electromagnetic space drive capable of getting to Mars in 70 days.

At least according to the Daily Galaxy.

It may not turn out that way though (on the face of it it breaks the laws of Physics which of course “You cannae change, Captain,”)* but it still makes me feel like I’m living in the future.

*From this clip Scotty actually said “can’t” rather than “cannae”:-

Pluto’s Volcanoes of Ice

From The Daily Galaxy 10/11/15. Pluto has ice volcanoes. (Some sort of false colouring here obviously.)

Pluto's Volcanoes

These two are called Wright Mons and Piccard Mons:-

Wright Mons and Piccard Mons

The ice may be a mixture of water ice, nitrogen, ammonia, or methane.

From Astronomy Picture of the Day 14/11/15 comes this photo of Wright Mons:-

Groovy Phobos

I got this one from The Daily Galaxy of 12/11/15.

Mars’s moon, Phobos, is groovy.

Grooves on Phobos

The grooves, and the depression shown below, are apparently due to the moon being slowly torn apart by gravitational tidal forces.
