Hope you learn a lot about space.
If you don't it's not my fault.
ikenbot: Kilimanjaro Fireball While an electric-lighted line of mountain climbers snakes toward it, a dazzling fireball (bright meteor) streaks over Tanzania’s Mount Kilimanjaro (the summit of Kibo at 5893 meters). — Kwon, O Chul
ikenbot: Dark Nebula LDN 810 This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. LDN 810 is a dark nebula that was first cataloged by B.T. Lynds in 1962. The dark region at the center contains gas and dust out of which new stars are forming. A bipolar outflow of gas from one of these stars has also been detected. A faint trail of dust and gas extends from the center of the image to the upper-left corner. The image was generated with observations in the Us (violet), B (blue), V (green) and I (red) filters. In this image, North is up, East is to the left.
spaceplasma: An Expanding Bubble in Space A star 40 times more massive than our sun is blowing a giant bubble of material into space. In this colorful picture, the Hubble Telescope captured a glimpse of the expanding bubble, dubbed the Bubble Nebula (NGC 7635). The beefy star [lower center] is embedded in the bright blue bubble. The stellar powerhouse is so hot that it is quickly shedding material into space. The dense gas surrounding the star is shaping the castoff material into a bubble. The bubble’s surface is not smooth like a soap bubble’s. Its rippled appearance is due to encounters with gases of different thickness. The nebula is 6 light-years wide and is expanding at 4 million miles per hour (7 million kilometers per hour). The nebula is 7,100 light-years from Earth in the constellation Cassiopeia.

n-a-s-a: Light Poles can be seen at nights over large cities with different colored lights. They can only be seen during very cold weather (the temperature of -20 Celsius degrees or lower is required), with minimal wind and plenty of tiny ice crystals in the atmosphere.

spaceplasma: Cassini’s Private Eclipse For this movie, Cassini pointed its cameras toward Dione to witness its distant sibling moon Rhea briefly pass behind in a series of 32 individual frames taken over 17 minutes. Four individual frames from the eclipse are shown at bottom.Rhea (1,528 kilometers, 949 miles across) is larger than Dione (1,123 kilometers, 698 miles across), but also is farther away as seen here – thus, the two moons appear to be roughly the same angular size.The view shows principally the anti-Saturn side of Dione, and the Saturn-facing side of far-off Rhea.

spaceplasma: Mimas Occults Janus Icy, impact-riddled Mimas (396 kilometers, 246 miles across) slips briefly in front of the moon Janus (179 kilometers, 111 miles across) in this movie from Cassini.The movie was created from 37 original images taken over the course of 20 minutes as the spacecraft’s narrow angle camera remained pointed toward Janus. Although Mimas moves a greater distance across the field of view, Janus also moved perceptibly during this time. The images were aligned to keep Janus close to the center of the scene. Additional frames were inserted between the 37 Cassini images in order to smooth the appearance of Mimas’ movement – a scheme called interpolation. Close-up images from the few minutes surrounding the occultation are arranged into a strip along the bottom of the GIF.The terrain on Mimas seen here is about 80 degrees to the west of that visible in a previously released movie, which showed the little moon appearing to cross Saturn’s ring plane from Cassini’s vantage point. In that previous movie, the rim of the large impact crater Herschel (130 kilometers, 80 miles wide) was visible as a flattening of the moon’s eastern limb. In the new movie, Herschel is almost at dead center.Contrast on Janus was mildly enhanced to aid the visibility of its surface. The right side of Mimas appears bright because the moon was partly overexposed in this image sequence. Credit: NASA/JPL/Space Science Institute
