Here we can inform each other of the situation of the masses in night sky and important astronomical events in future and discuss about their conditions

Saturday, April 28: The position of Mars in Leo
Mars remains a conspicuous point of light among the background stars of Leo the Lion. It stands high in the south as darkness falls and doesn’t set until after 3 a.m. local daylight time. Shining at magnitude –0.1, it easily bests Leo’s brightest star, 1st-magnitude Regulus.

Monday, April 30: The position of Venus in the western sky
Venus appears brilliant in the western sky starting about half an hour after sunset. It stands one-third of the way to the zenith 30 minutes after the Sun goes down and doesn’t set until nearly 11:30 p.m. local daylight time. Shining at magnitude –4.7, it appears slightly brighter today than at any other time during this evening apparition. (The difference is essentially imperceptible, however — it appears only a thousandth of a magnitude brighter today than it did yesterday or will tomorrow

Wednesday, May 2: Hebe near Mars
This week offers a last chance to track down asteroid 6 Hebe through your telescope. The 11th-magnitude space rock lies 9° north of Mars, but it is easier to find by scanning about 1° east-northeast of the fine double star Gamma (γ) Leonis, which shines at 2nd magnitude

Thursday, May 3: The posotion of Saturn in Virgo
Saturn reached its peak when it appeared opposite the Sun in our sky April 15, but our view of the ringed planet remains spectacular. It is on display all night among the background stars of Virgo, hanging in the southeastern sky as darkness falls and climbing high in the south by midnight local daylight time. Saturn continues to shine brightly, too, at magnitude 0.3. It appears brighter than Virgo’s brightest star, Spica, which lies 5° southwest of the planet

Friday, May 4: Eta Aquarid meteor shower
The annual Eta Aquarid meteor shower peaks tomorrow morning. Unfortunately, Full Moon arrives May 5, and its bright light will wash out fainter meteors and render the brighter ones less impressive. Don’t give up hope, however. The shower’s radiant — the point from which the meteors appear to emanate — rises in the east around 3 a.m. local daylight time. With the Moon then in the western sky, position yourself where buildings or trees block its light. The Eta Aquarid shower derives from bits of debris ejected by Comet 1P/Halley during its many trips around the Sun
Usually, the days before and after maximum offer observers with access to a dark observing site up to 30 meteors per hour. This number jumps to 60 per hour at the shower’s peak the morning of May 5..

Monday, May 7: The position of Mars in Leo
Mars remains prominent among the background stars of Leo the Lion. It stands high in the south as darkness falls and doesn’t set until after 3 a.m. local daylight time. Shining at magnitude 0.1, it easily bests Leo’s brightest star, 1st-magnitude Regulus. Also note the stark color contrast between ruddy Mars and blue-white Regulus.

Tonight's event is about a deep sky object. To hunt this object all you need to enjoy this gem is a dark sky and two eyes
Do you feel in the mood for a nice springtime galaxy? With binoculars in hand, scan the border between Hydra and Centaurus, about two-thirds of the way from 3rd-magnitude Gamma (γ) Hydrae to 4th-magnitude 1 Centauri. Spiral galaxy M83 shows a bright stellar nucleus surrounded by the soft glow of its broad spiral arms. For observers at 40° north latitude, M83 climbs 20° above the southern horizon around 1 a.m. local daylight time

Wednesday, May 9:The posotion of Saturn in Virgo
Although Saturn reached its peak nearly a month ago when it appeared opposite the Sun in our sky, our view of the ringed planet remains spectacular. It is on display all night among the background stars of Virgo, hanging in the southeastern sky as darkness falls and climbing high in the south by 11 p.m. local daylight time. Saturn continues to shine brightly, too, at magnitude 0.4. It appears noticeably brighter than Virgo’s brightest star, Spica, which lies 5° south-southwest of the planet

Thursday, May 10: Comet Garradd near spiral galaxy NGC 2683
Comet C/2009 P1 (Garradd) currently glows around 8th magnitude among the background stars of southeastern Lynx. Although this constellation features no star brighter than 3rd magnitude, the region is easy to locate south of the front legs of Ursa Major the Great Bear. This evening, Garradd provides a bonus because it passes less than 1° west of the nearly edge-on spiral galaxy NGC 2683. You’ll need a telescope for good views of the comet and galaxy

Friday, May 11: The Big Dipper lies nearly overhead
The Big Dipper’s familiar shape lies nearly overhead on May evenings. The spring sky’s finest binocular double star marks the bend of the Dipper’s handle. Mizar shines at 2nd magnitude, some six times brighter than its 4th-magnitude companion, Alcor. Although these two are not physically related, they make a fine sight through binoculars. (People with good eyesight often can split the pair without optical aid.) A small telescope reveals Mizar itself as double — and these components do orbit each other
