I recently got to view this through my very own telescope, super exciting!!
Star cluster, Pleiades.

Why…
Astronomy compels the soul to look upward, and leads us from this world to another

For all your stargazing pleasures
Jupiter, Mars, the Lyrid meteor shower and 2016’s best views of Mercury are all visible in the sky this month.
Jupiter, where our Juno mission will begin orbiting on July 4, continues to shine almost as brightly this month as last. And eagle-eyed telescope viewers will see a transit, a shadow transit, an occultation and an eclipse of Jupiter’s moons- all in one night: April 6-7.
Io transits first, crossing the planet beginning at 9:52 p.m. EDT. It’s shadow can be seen less than an hour later.
Next Jupiter occults, or eclipses, Europa as Europa slips behind the giant planet at 10:48 p.m. EDT. At 3 a.m. Europa reappears from its eclipse, dramatically leaving the shadow of Jupiter.
Ganymede transits the planet beginning at 1:01 EDT April 7.
Check out the other planets in April, too! Mercury is always a challenging object to view, but this month you can spot it after sunset about 10 degrees above the horizon. Through a telescope you can see its phase. It will appear like a tiny crescent moon, with about 1/3 of its disk illuminated.
Mars is finally visible before midnight this month. It rises in the southeast at about 10 p.m. by the end of April. The best observing of Mars will be when it is highest in the sky. This means a few hours before dawn. Its brightness and apparent size increase dramatically this month. By month’s end, Mars appears nearly twice as bright as at the beginning of the month.
About mid-month you’ll see Mars near its rival in the sky: the similar-colored red supergiant star Antares. The name “Antares” means “equal to or rival of Mars”.
Earth moves almost twice as fast as Mars does, so it often passes Mars in their race around the sun. This causes “retrograde motion”: an illusion we see from our viewpoint on Earth.
Retrograde motion happens as Earth catches up to Mars, causing Mars to appear slow to slow its eastward motion against the stars. After a few days, when Earth has overtaken Mars, the Red Planet seems to move westward. Eventually, Earth moves far enough around its orbit that Mars appears to be moving eastward again.
April features one meteor shower, the Lyrids. This year the Lyrids are marred by the full moon. The best time to view will be just before dawn on April 23, when the constellation Lyra is overhead and the moon will be near to setting.
With all of these great things to spot in the sky this month, be sure to get outside and look up!

Cassini Approaches Saturn
(via APOD; Image Credit: Cassini Imaging Team, SWRI, JPL, ESA, NASA )
Cassini, a robot spacecraft launched in 1997 by NASA, became close enough in 2002 to resolve many rings and moons of its destination planet: Saturn. At that time, Cassini snapped several images during an engineering test. Several of those images were combined into the contrast-enhanced color composite featured here. Saturn’s rings and cloud-tops are visible toward the image bottom, while Titan, its largest moon, is visible as the speck toward the top. When arriving at Saturn in July 2004, the Cassini orbiter began to circle and study the Saturnian system. A highlight was when Cassini launched the Huygens probe that made an unprecedented landing on Titan in 2005, sending back detailed pictures. Now nearing the end of its mission, Cassini is scheduled to embark on a Grand Finale phase in late 2016 where it will repeatedly dive between the giant planet and its innermost rings.
This is the cutest thing I’ve seen in so long.
Never fails to amaze me
