It Came From Outer Space…..

Astronomers have discovered the first object from outside the solar system ever to have been observed travelling through it.

A photograph of it is at Astronomy Picture of the Day for 3/11/17.

It was reported in the journal Nature on 31/10/17.

The Nature article quotes “Rights and Permissions” for use so I have not reproduced it here but both links show the object, known as interstellar asteroid A/2017 U1.

An analysis of it movement is at https://arxiv.org/abs/1710.11364.

Beautiful Celestial Jewel

Check out this gem from Astronomy Picture of the Day, 12/10/17. It’s a picture of barred spiral galaxy NGC 1365 apparently in visible light (as opposed to infra-red or UV or radio images.) I haven’t reproduced it here as it’s not the usual copyright.

But it’s a lovely scene just the same.

An Ice Ring Around Fomalhaut

The amazing image below (from Astronomy Picture of the Day, 3/10/17) is of a ring of ice around the star Fomalhaut which also has at least one planet. The planet has even been given a proper name, Dagon.

The image of the ring is courtesy of the Atacama Large Millimeter Array and is superimposed on a hubble picture of the Fomalhaut system in blue.

This thing is 25 light years away yet we are able witness it in such detail (albeit at radio wavelengths.)

Solar Eclipse in Close-Up

Again from Astronomy Picture of the Day; this time for 12/9/2017.

Look how pink those solar prominences are.

Approaching Saturn

A fine video – as shown in Astronomy Picture of the Day for 11/9/2017 and made by amalgamating individual pictures – of one of the Cassini probe’s passes through the Saturn system.

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.)

Earth from Saturn

A stunning picture of Saturn’s rings backlit by the sun from yesterday‘s Astronomy Picture of the Day. And between them the spot of light is Earth with the tiny pinprick to its left, the Moon.

This is a view that would have been difficult to imagine seeing when I was a lad.

Pan from Cassini

Nasa’s Cassini probe has produced an intriguing close-up view of Saturn’s moon Pan.

This photograph is today’s Astronomy Picture of the Day.

Pan from Cassini

Pan orbits inside the the Encke Gap of Saturn’s A-ring but is an odd object indeed.

Exo-Planets in Motion

This is stunning. From Astronomy Picture of the Day, 1/2/2107.

A time-lapse video, taken over seven years, of Four Planets Orbiting Star HR 8799. (The system’s central star itself has been occluded to allow the planets to be seen.)
