Uranus is observable only right after sunset in Pisces, but looks little (3.7 as) and faint (5.7 mg) in the telescope.
Jupiter is up at 7pm, and it is great in a telescope.
1. Philae, a space probe off the Rosetta spacecraft,
has landed on comet Churiumov-Gerasimenko after bouncing up twice.
It seems it landed in a hole, and hybernating for lack of power.
An important result of the mission: Earth's water did not originate in comets.
2 The ALMA radio telescope array reveals a super-high resolution image of planet formation.
3. Meteor impact carve new craters on Mars.
4. Jupiter's Great Red Spot is shrinking and fading?
5. J0159+0033, a 19-mg quasar in Cetus, has faded 2 mg in ten years.
Its accretion disk is now depleted: it is switching off!
Unusual events and objects
Comet C2014/Q2 (Lovejoy) is 5 mg in Andromeda, up early night.
Look at some pretty pictures of this comet!
For observation, a pair of binoculars would be needed. Use the star chart in the article in the link.
