Take a Deep Dive into Deep Space

   Take a deep dive into deep space at the DESI Legacy Imaging Surveys web site. This is an interactive display using a 10 trillion pixel composite picture of much of the night sky, based on different imaging data sets to create the image. The zoom-in is incredible as the billions of points of light resolve into galaxies, nebulae and other deep sky objects. Some of the datasets even show a spectral display. There are a number of ways to interact with the images including a way to flip back and forth between two images to watch for any objects in motion. Clicking on the screen will bring up options for joining a forum to ask or discuss what you are viewing. There are links to other information about that object or part of the sky.
   The video is a short tour of around Taurus and Orion.

Minor Planet, Asteroid 4 Vesta at Opposition

   Wednesday 9 May the minor planet, Asteroid 4 Vesta will be at its perihelion for this orbit. Perihelion is when a solar orbiting object is at its minimum distance, or closest to the Sun. Asteroid 4 Vesta is one of the largest main belt asteroids with a diameter of about 525 km (326 miles).

   At this perihelion 4 Vesta will be 2.1517 AU (321,889,738 km; 200,013,010 miles) from the Sun. At this distance 4 Vesta will reach an apparent magnitude of around 6.0 meaning that it could be visible using binoculars. 4 Vesta lies within the region of the Milky Way and about 1o from 4 Vesta is the Omega Nebula, M-17 (apparent magnitude 7.0), and around 4o from 4 Vesta is the Eagle Nebula, M-16 (apparent magnitude 6.5).
