Earth (and Moon) From Space

Far out (as they say) gives a particular view of Earth and its Moon.

Astronomy Picture of the Day on 23/11/24 showed a composite of two photographs of Earth from the vicinity of other planets. A picture taken from near Saturn by the Cassini probe and another from Mercury orbit taken by Messenger:-

 

 

 

 

 

 

 

 

 

 

 

Such a small dot in a big universe.

Valles Marineris

I never tire of seeing pictures of this feature of the surface of Mars. Valles Marineris, the largest canyon in the Solar system. This one was taken by NASA’s Viking probe and was Astronomy Picture of the Day‘s post for 10/12/24.

A Solar Prominence in Motion

Imagine the violence of this. A solar prominence erupting in 2011. This time-lapse video covers 90 minutes (one new frame every 24 seconds.) It was captured in ultra-violet light by NASA’s Solar Dynamic Observatory. From You Tube via Astronomy Picture of the Day for 18/8/24.

An Erupting Volcano Against the Night Sky

From YouTube via Astronomy Picture of the Day for 17/7/24.

Thsi is quite an arresting time-lapse video. Villarico volcano in Chile against a backdrop of the Milky Way and Magellanic Clouds:-

 

The Moon in Rotation

A video from YouTube via Astronomy Picture of the Day for 2/6/24.

From Earth, the Moon, because it is tidally locked, seems stationary. This representation is assembled from photos taken by the Lunar Reconnaissance Orbiter (LRO) and shows a full rotation of the Moon condensed into 24 seconds.

Flying Through the Great Red Spot

Jupiter’s Great Red Spot is one of the most distinctive atmospheric features in the Solar System.

This video is from YouTube via Astronomy Picture of the Day for 19/5/24.

An animation based on data from the JunoCam imager on NASA’s Juno spacecraft with a computer-generated animation.

 

Black Hole Accretion Disc

From You Tube via Astronomy Picture of the Day for 8/5/24.

Not real of course, just an animation, but it shows the weird effects of the black hole’s gravity on the light emanating from the disc.

 

End of an Eclipse

From YouTube via Astronomy Picture of the Day for 14/4/24 comes this video of the end of this month’s solar eclipse, First the so-called diamond ring then the blobs of light known as Bailey’s Beads. All over in less than ten seconds.

A Double Moon Eclipse

By which I mean one moon eclipses another.

Neither is Earth’s Moon of course.

Via Astronomy Picture of  the Day for 26/2/24 this is Mars’s moon Phobos eclipsing its other moon, Deimos, as seen by European Space Agency‘s probe Mars Express.

A Ring of Stars

Isn’t this beautiful?

 

 

 

 

 

 

 

 

 

 

 

 

 

The picture is from Astronomy Picture of the Day for 18/2/24, via the Hubble Telescope. It’s a ring galaxy, called Hoag’s Object after the man who discovered it.

Amazingly there is another ring galaxy in the background behind the circle of stars, at about seven o’clock in the main picture.
