image noise, photographed / not photographed by soho, 14th june 2015.

35 frames, photographed over 7.5 hours, with the subject of the images removed as much as possible; some traces of the background stars remain, however. near centre, elnath (beta tauri) is somewhat visible as a crescent. most of the noise is from charged particles hitting the image detector.

berlin: Sun, stars, and Mercury, photographed by SOHO, 15th June 2014.

1 photo per hour for 24 hours. Mercury is between Earth and the Sun.

“Alnath” is derived from the Arabic النطح (“the butting”, as of the bull, Taurus), also rendered Elnath or El Nath. Since it is the second brightest star in Taurus, it is also known as Beta Tauri (or β Tau). Before the modern borders of the constellations were defined, Alnath was also sometimes considered to be shared with the neighboring constellation of Auriga, earning it yet another designation; Gamma Aurigae (γ Aur).

NGC 1746 is the New General Catalogue number for the loose group of stars seen at far right. At the time of their designation in 1863, the stars were thought to be an open cluster - gravitationally bound and probably sharing an origin. More recent studies show that they are not related, and only appear as a group from Earth’s perspective.

So here’s the deal: I need to take these pictures with what I’ve got: a three-year-old iPhone 4 camera.

Anyways the top image is Comet Lovejoy. When you look at it with an 8" telescope or smaller (you can see it with binoculars) it just looks like a really bright, green star (the comet’s green due to a presence of diatomic carbon).

When I look with the naked eye I couldn’t really make anything out. It’s bright in the telescope though. If you want to look for Lovejoy yourself it’s currently in the vicinity of the constellation Auriga, a bit South of the star Beta Tauri/Elnath.

Since the first picture is a bit shoddy though I took a photograph of Jupiter and three of its moons for you. I’m not sure which was behind Jupiter but it looks to be either Europa or Io (* i-am-the-last-timelord, thanks! That’s a cool program - Callisto is the hidden moon, the other three are visible).

The phone’s camera doesn’t do Jupiter justice either… I can plainly see the bands of wind going across the outer layers of the planet. Hopefully one day I’ll be able to provide a decent image for you guys
