Monthly Stargazing Calendar for June 2012
Today on June 5 we will have the chance to witness the transit of Venus across the Sun. This extremely rare event will be entirely visible throughout most of eastern Asia, eastern Australia, and Alaska.
Monthly Stargazing Calendar for May 2012
On May 5, 6 we witnessed the Eta Aquarids Meteor Shower. It is a a light shower, usually producing about 10 meteors per hour at the peak. The full moon ruined the show this year, washing out all but the brightest meteors with its glare.
Monthly Stargazing Calendar for April 2012
On April 15 the planet Saturn will be at Opposition. The ringed giant will be at its closest approach to the Earth and its face will be fully illuminated by the Sun. It will be the best time to view and photograph Saturn and its moons.
Monthly Stargazing Calendar for March 2012
On March 3, Mars was at opposition. The Earth passed Mars as the two planets wheeled around the sun in their respective orbits. This time the opposition was an unfavorable one because Mars was at aphelion on February 15, which means it was at its farthest point from the sun.
Monthly Stargazing Calendar for February 2012
The best chance to see Mercury will be from February 20 to March 12. The planet will, from our point of view, have moved far enough from the Sun's glare to be visible shortly after sunset. Mercury will reach greatest elongation from the Sun on March 5, reaching a relatively bright magnitude of about -1.
Antennae Galaxies – Astronomy Picture of the Week
This beautiful image of two colliding galaxies has been released by NASA's great observatories. The Antennae galaxies are located about 62 million light-years from Earth. They take their name from the long antenna-like "arms," which were produced by tidal forces generated in the collision.
15 Things You Didn’t Know About Outer Space [Infographic]
Since the dawn of history, outer space has always caught the imagination of people across the continents and different cultures. However most of what we currently know about space has been discovered since the beginning of the space age over half a century ago.
Dark Matter Map in Galaxy Cluster Abell 1689 – Astronomy Picture of the Week
This image represents the inner region of galaxy cluster Abell 1689 and the distribution of dark matter around it. Abell 1689 is an immense cluster of galaxies located 2.2 billion light-years away. Dark matter cannot be photographed, but its presence can be inferred by observing the light from background galaxies…
Monthly Stargazing Calendar for January 2012
On the night of January 3 to 4 the Quadrantids meteor shower will peak. It is an above average shower, with up to 40 meteors per hour at the peak. The near first quarter moon will interfere with the show a little at first, but it will set shortly after midnight, leaving dark skies for what would then be a good show.
Monthly Stargazing Calendar for December 2011
On December 10 we will witness a total lunar eclipse. The best viewing location will be in the Asia-Pacific region, but the eclipse will still be visible throughout most of Europe, eastern Africa, Asia, Australia, the Pacific Ocean, and North America. Unfortunately the eclipse will not be visible in South America.
Monthly Stargazing Calendar for November 2011
This month we are expecting the flyby of Asteroid 2005 YU55. On November 8th, it will make a close approach to the Earth at 0.85 lunar distances. It has a diameter of about 400 meters so unfortunately it is too small to be visible to the naked eye.
Panoramic View of the Orion Nebula – Astronomy Picture of the Week
This image, taken by NASA's Hubble Space Telescope, represents the sharpest view ever taken of the Orion Nebula. More than 3,000 stars of various sizes appear in this image. The bright central region is the home of the four largest stars in the nebula.
