Took these photos last night using my phone, held up to various telescopes at the YAS observatory. Just goes to show you don’t need to have expensive equipment to take photos of space. :)
Top left: Venus as a pretty little crescent. :)
Top right: Mars, not a brilliant photo but it was the only one I took of it and wanted to post it anyway.
Bottom: Saturn, a lot better than my previous attempts so I’m pretty proud of this one. :D
Hubble to Watch Historic Venus Transit, Using Moon as Mirror
Scientists are planning to use NASA’s Hubble Space Telescope to observe next month’s historic transit of Venus across the sun’s face.
But there’s a twist. Researchers can’t point Hubble anywhere near the sun, because our star’s bright light could damage the telescope’s super-sensitive instruments. So Hubble will watch the June 5-6 Venus transit by using the moon as a mirror.
The goal is to see if Hubble can determine the makeup of Venus’ atmosphere by studying sunlight that has poured through it. Astronomers already know a great deal about Venus’ air, so next month’s observations are a test run to see if the technique could be used to determine the atmospheric composition of faraway alien planets, researchers said.
Scientists hope the method can help them find an “alien Earth,” a habitable planet much like our own, orbiting a distant star. Venus is an excellent proxy for this search because it’s nearly the same size and mass as Earth, researchers said.
hmmm interesting :)
Terrestrial Planets
Also known as rocky planets, these bodies are composed primarily of rock and metal and have very high densities. They also tend to be relatively small in size and have slow periods of rotation. The terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars. They are the planets closest to the Sun. Terrestrial planets tend to have very few natural satellites, or moons. Of the four terrestrial planets in our solar system, only two have moons. Earth has one moon while Mars has two.

Venus and the Sisters

Explanation: After wandering about as far from the Sun on the sky as Venus can get, the brilliant evening star crossed paths with the Pleiades star cluster earlier this week. The beautiful conjunction was enjoyed by skygazers around the world. Taken on April 2, this celestial group photo captures the view from Portal, Arizona, USA. Also known as the Seven Sisters, even the brighter naked-eye Pleiades stars are seen to be much fainter than Venus. And while Venus and the sisters do look star-crossed, their spiky appearance is the diffraction pattern caused by multiple leaves in the aperture of the telephoto lens. The last similar conjunction of Venus and Pleiades occurred nearly 8 years ago. As it did then, Venus will again move on to cross paths with the disk of the Sun in June.
Zodiacal Light Panorama

Explanation: Sweeping from the eastern to western horizon, this 360 degree panorama follows the band of zodiacal light along the solar system’s ecliptic plane. Dust scattering sunlight produces the faint zodiacal glow that spans this fundamental coordinate plane of the celestial sphere, corresponding to the apparent yearly path of the Sun through the sky and the plane of Earth’s orbit. The fascinating panorama is a mosaic of images taken from dusk to dawn over the course of a single night at two different locations on Mauna Kea. The lights of Hilo, Hawaii are on the eastern (left) horizon, with the Subaru and twin Keck telescope structures near the western horizon. On that well chosen moonless night, Venus was shining as the morning star just above the eastern horizon, and Saturn was close to opposition. In fact, Saturn is seen immersed in a brightening of the zodiacal band known as the gegenschein. The gegenschein also lies near 180 degrees in elongation or angular distance from the Sun along the ecliptic. In the mosaic projection, the plane of our Milky Way Galaxy runs at an angle, crossing the horizontal band of zodiacal light above the two horizons. Nebulae, stars, and dust clouds of the bulging galactic center are rising in the east.
Astrophotos from Around the World of the Venus-Pleiades Conjunction
The past several evenings, Venus has been snuggling up to one of the most famous star clusters, the Pleiades. Universe Today readers have taken some beautiful images of that event, and they have generously shared them with us. Above is John Chumack’s stunning view from Ohio in the US; see below for more images from around the world!
The Pleiades, also known at the Seven Sisters, is a beautiful bright blue open star cluster 440 light years from Earth. Only once every eight years does this conjunction take place.
John Anton took this pretty image from New Jersey in the US. “It was a beautiful sight,” he said.
Astronomers say that the relative tightness of the cluster indicates this is a young group of stars, and the member stars were formed about 100 million years ago and will probably travel together through space as a bound cluster for another 250 million years before the gravity of the Milky Way breaks up the cluster into individual field stars.
“An old SLR 70-210mm zoom lens on my DMC-G10. 5 second exposure, 1600 ISO. Tree illuminated partly by a neighbours light and partly by the built in flash on the camera,” says Dave Liddicott.

Paris by Night
Image Credit & Copyright: Serge Brunier (TWAN)
Explanation: Do you recognize the city lights of Paris in this picture? Taken on March 25 from the top of the 210 meter tall Montparnasse skyscraper, many will spot the looming Eiffel Tower, or the large domed structure of Les Invalides (right), or the colorfully lit elevated Metro train line gently curving toward picture center. You can even pick out the Arc de Triomphe close to the horizon on the right. But regardless of your location, the celestial lights near the western horizon should look very familiar. The lovely triple conjuntion of brilliant Venus (top), Jupiter, and a young crescent Moon was visible in evening skies around planet Earth.
The Grand Canyon in Moonlight

Explanation: In this alluring night skyscape recorded on March 26, a young Moon stands over the distant western horizon in conjunction with brilliant planet Venus. In the foreground, the Colorado River glistens in moonlight as it winds through the Grand Canyon, seen from the canyon’s southern rim at Lipan Point. Of course, the Grand Canyon is known as one of the wonders of planet Earth. Carved by the river, the enormous fissure is about 270 miles (440 kilometers) long, up to 18 miles (30 kilometers) wide and approaches 1 mile (1.6 kilometers) deep. On this date, wonders of the night sky included the compact Pleiades and V-shaped Hyades star clusters poised just above the Moon. Bright planet Jupiter is below the closer Moon/Venus pairing, near the western horizon.
Earthshine and Venus Over Sierra de Guadarrama

Explanation: What just above that ridge? The Moon. Specifically, the Earth’s Moon was caught just above the horizon in a young crescent phase. The familiar Moon might look a bit odd as the exposure shows significant Earthshine — the illumination of the part of the Moon hidden from direct sunlight by the sun-reflecting Earth. Also captured in the image is the bright planet Venus on the right. Venus and Jupiter passed only three degrees from each other last week during a photogenic planetary conjunction. The above image was taken two days ago near Madrid, Spain. The foreground horizon silhouette includes some of the Seven Peaks of the Sierra de Guadarrama mountain range. Just a few minutes after this picture was taken, the Moon set.
