Hubble Reaches the "Undiscovered Country" of Primeval Galaxies
NASA's Hubble Space Telescope has broken the distance limit for galaxies and uncovered a primordial population of compact and ultra-blue galaxies that have never been seen before Link
HIRISE - This peak consists of rocks originating from several kilometres beneath the pre-impact surface. Mojave has a very prominent central uplift as it has a diameter of 60 kilometres (37 miles). In this image, boulders as large as 15 meters (50 feet) across have been eroded from the massive uplifted rock and have rolled down slope. Fine-grained debris has also collected in the topographic lows, and has been shaped by the wind into dunes and ripples link

Blemished by Mimas

A pastel crescent of Saturn is interrupted by the moon Mimas and the rings in this colour image.
Mimas (396 kilometres, or 246 miles across) appears as a dark speck just above the rings. This view looks toward the northern, sunlit side of the rings from just above the ringplane link

Dark Quartet

The Cassini spacecraft gazes at several albedo features on Saturn's largest moon, Titan.
Left to right are four dark regions: Fensal, Aztlan, Aaru and a part of Senkyo. The bright area Quivira lies near the centre of the image, separating Fensal and Aztlan. This view looks toward the Saturn-facing side of Titan (5,150 kilometres, or 3,200 miles across). North on Titan is up and rotated 24 degrees to the right link

The Sun - is in Pisces. It rises at 06:23, transits the meridian at 12:19, and sets at 18:16. The length of the day is 11h 53m

 


Venus - is in Pisces with a magnitude of -3.9, a phase of 97%, and a diameter of 10". It rises at 06:55, transits at 13:17, and sets at 19:40. It is visible low in the west after sunset


Mars - is in Cancer with a magnitude of -0.2, a phase of 94%, and a diameter of 11". It sets at 05:17, rises again at 12:20, and transits at 20:47. It is visible in the evening sky


Uranus - is in Pisces with a magnitude of +5.9 and a diameter of 3". It rises at 06:31, transits at 12:23, and sets at 18:14. It is currently too close to the Sun to be observed.

 
Mercury - is in Pisces with a magnitude of -1.8, a phase of 100%, and a diameter of 5". It rises at 06:36, transits at 12:28, and sets at 18:22. It is currently too close to the Sun to be observed

Jupiter - is in Aquarius with a magnitude of -2.0 and a diameter of 33". It rises at 06:12, transits at 11:35, and sets at 16:59. It is visible low in the east before sunrise


Saturn - is in Virgo with a magnitude of +0.5 and a diameter of 19". It transits at 00:47, sets at 06:58, and rises again at 18:31. It is well placed for observation throughout the night


Neptune - is in Capricornus with a magnitude of +8.0 and a diameter of 2". It rises at 05:41, transits at 10:33, and sets at 15:25. It is visible low in the east before sunrise
 
   
 
 

Meteors - On any clear night, we may see the occasional meteor or “shooting-star”, as tiny specks of interplanetary débris burn up in the Earth’s atmosphere. At certain times of the year, the Earth travels through a cloud of this dust, and we get a meteor-shower. However, there are no significant meteor-showers in March, and it is generally a quiet time for sporadic meteors too

The next major shower is the Lyrids, which are active between April 16 and April 25, with the maximum on April 22 at a ZHR of 18. The swift and bright Lyrid meteors disintegrate after hitting our atmosphere at a moderate speed of 29.8 miles per second. They often produce luminous trains of dust that can be observed for several seconds

There are also the Eta Aquarids, active from April 19 to May 28, with a maximum on May 6 with a ZHR of 85
