Comet Lovejoy on May 22, 2015. The comet is the brilliant green dot near the center of the photo. At the upper right of the photo is the star Polaris, aka the North Star.
The comet was 51 million miles from Earth at the time – a short distance for the Dark Energy Camera, which is sensitive to light 8 billion light-years away.
Ever-photogenic Comet Lovejoy at its closest to the Seven Sisters, or Pleiades, star cluster. The comet's long blue ion tail stretched back past the cluster.
How to see Comet C/2014 Q2 Lovejoy - still visible through binoculars and telescopes. Finder charts and best photos!

Comet Lovejoy came faintly visible to the eye in early November 2013. It was closest to the sun on December 22. It's currently on the outbound leg of its orbit.
Around mid-December, Comet Lovejoy is near the famous Keystone asterism in the constellation Hercules. Photos and charts here.
Astronomers used the Subaru Telescope to capture this image of Comet Lovejoy's tail on December 3, 2013. This comet is now visible in earthly skies.
Comet Lovejoy has been visible with binoculars in the predawn sky, near the famous Beehive star cluster. How to spot it, plus best photos, here.
Australian amateur astronomer Terry Lovejoy has discovered a new comet. The new Comet Lovejoy will occupy the same part of the sky as Comet ISON by November 2013.

As it swept near the sun in early December 2011, Comet Lovejoy defied expectations and survived its close pass of the sun to become a Christmas comet.
There's a nice binocular comet - Comet NEOWISE - in the early morning sky now. Some experienced observers are catching it with the eye alone. It's nice ... but not great. When will we see our next great comet?
This faint comet - Comet C/2019 U6 (Lemmon) - is headed toward its perihelion, or closest point to the sun, on June 18. It's currently visible from the Southern Hemisphere, via strong binoculars, with a dark sky.
Comet C/2019 Y4 (ATLAS) was getting brighter. Then, sadly, the Hubble Space Telescope caught it apparently disintegrating. Now ... surprise. Veteran comet observer Terry Lovejoy reported earlier today that the comet is brightening again!
Look here for photos and video of 2018's Christmas comet and brightest comet, 46P/Wirtanen.
SOHO - Solar and Heliospheric Observatory - is the greatest comet-discoverer of all time. It has found 3,000 comets ... but our sun has destroyed nearly all of them.
The close pass of Comet Siding Spring to Mars was exciting! Closest approach was October 19. Watch for photos from the event here at EarthSky.org.
Comet ISON is now thought to be a traveling debris field, with no solid nucleus or core. Will we see the debris field from Earth? No one knows yet.
ISON's moment of truth is here - its closest approach to the sun - today. Here are some ways to experience it online.
