Full Moon Over Lick Observatory

A lovely nightscape of the "Full Flower Moon" over the venerable Lick Observatory on Mount Hamilton near San Jose, California. The observatory was the world's first permanently occupied mountaintop observatory. It houses, among many other telescopes, the great 36" refractor telescope used by astronomers to discover 25 comets, 1300 double stars, and the first estimate of the density of the atmosphere of Mars.

Bright Spots on Ceres Return To View

As NASA’s Dawn orbiter approached the Ceres in late February, it released tantalizing images of a pair of bright spots on the floor of a big crater of the dwarf planet. But after the craft began orbiting Ceres on March 6, 2015, the newsfeed went silent. Conspiracy theories started brewing, naturally, about how the government was keeping secret the discovery of (fill in the blank) on Ceres.

It turns out the spacecraft was just settling in and was mostly over the dark side of the dwarf planet. Now NASA has released two new images of Ceres, including the still mysterious bright spots, taken from Dawn on April 14 and 15 from 14,000 miles above Ceres’ north pole.

Why Now is the Best Time To Be A Stargazer

Some argue because of widespread light pollution that the best days for amateur astronomy are behind us. But take heart, fellow stargazer, because in this article, you discover why this is the best time in history to enjoy the night sky...

Venus Continues to Brighten

Venus setting (lower left) amid light pollution (the orange color at left) and a faint red auroral display (right) over downtown Ottawa, Canada. The planet continues to brighten and draw closer to Jupiter in the western sky after sunset.

From the Observer's Log: NGC 5907

Out looking at galaxies last night, and this is one of my favorites. Here's a note from the 'observer's log' about NGC 5907, the 'Splinter Galaxy'.

Mercury, the Pleiades, and the Hyades

The clouds parted in time to snap Mercury (middle right) and the Pleiades (further right) after sunset on May 1, 2015. The Hyades star cluster is tangled in the branches at left. For the next week, the speedy little planet is making its best appearance this year in the western sky after sunset.

See the Eta Aquariid Meteor Shower Next Week

The usually reliable Eta Aquarid meteor shower peaks on the night of May 5-6 this year. It is perhaps the best meteor shower of the year for southern hemisphere stargazers, and it's pretty good for northerners too. The Full Moon on May 4 will get in the way of some of the shower, but you can catch meteors for several days before and after the peak of the Eta Aquariids.

Chandra's Limit

In which I recall a brush with astronomical greatness, and try to explain why there are no fat white dwarfs (yes, they are related... sort of).

A Surprising Large-Scale Alignment of Quasars
In a remarkable discovery, astronomers using ESO’s Very Large Telescope (VLT) in Chile have discovered that quasars separated by billions of light years are aligned parallel to each other, as if they were under the influence of an unseen mechanism that gets them pointing in the same direction. This mechanism seems to be related to the largest-scale structures in the universe, the vast filaments of galaxy clusters that form around voids and bubbles were very few galaxies are found.
