      Perseid radiant. The radiant is the area where the meteors in a shower seem to originate. People in the northern hemisphere get the best view of the Perseids because in the southern hemisphere the radiant is below the horizon. Southern hemisphere observers can still see a worthwhile number of meteors coming up from the horizon. Mona Evans, "Meteor Shower - the Perseids"

    Did you know that up to 4,000,000,000 meteoroids fall to our planet every single day. Most of them burn in the Earth's atmosphere, however, some of them impact with the surface. This infographic will show you 5 largest meteorites on our planet.

    ▶ B612 Impact Video. Between 2000 and 2013, a network of sensors that monitors Earth around the clock listening for the infrasound signature of nuclear detonations detected 26 explosions on Earth ranging in energy from 1-600 kilotons -- all caused not by nuclear explosions, but rather by asteroid impacts. Let's do something to protect ourselves!

    Map-projected view of Ceres. It was created from images taken by NASA's Dawn spacecraft during its initial approach to the dwarf planet. It reveals the diversity of the surface of this planetary body. Differences in morphology and color across the surface suggest Ceres was once an active body.

    Ceres photographed on May 2-4 by the Dawn spacecraft. The “pair” of bright spots in this crater turn out to be made up of more spots. It looks as though they're created by sunlight reflecting off very reflective material, possibly ice. But there will be more data to come.

    Asteroid 316201 has been named by its discoverer, NASA astronomer Amy Mainzer. She named it for Malala Yousafzai, a Pakistani teenager who campaigns for education for girls. She's 17 and has already survived an assassination attempt by the Taliban and been awarded a Nobel Prize. The asteroid is circled.

    Ceres. Image taken by NASA's Dawn spacecraft of the dwarf planet on Feb. 19 from a distance of nearly 29,000 miles (46,000 km). It shows that the brightest spot on Ceres has a dimmer companion, which apparently lies in the same basin.

    Geminids 2014. Taken from the summit of Mt. Changbai as a composite of digital frames capturing bright meteors near the shower's peak. Orion is near picture center above the volcanic cater lake. The shower's radiant in the constellation Gemini is to the upper left. The photographer encountered severe wind gusts and minus 34 degree C temperatures near the summit.

    Geminids 2014. View from mid-southern latitudes at about 11:00 p.m. local time around December 13. The graphic doesn't represent the view at the time of maximum, it's just meant to help observers find the radiant location. The red line across the bottom of the image represents the horizon. Although the actual radiant is below the horizon, the stars just above the horizon are those of the constellation Perseus. (Image produced by Gary W. Kronkr using SkyChart III and Adobe Photoshop.)

    Geminids 2014. View from mid-northern latitudes at about 9:00 p.m. local time around December 13. The graphic doesn't represent the view at the time of maximum, but is just meant to help prospective observers find the radiant location. The red line across the bottom of the image represents the horizon. (Image produced by Gary W. Kronk using SkyChart III and Adobe Photoshop.)

    Willamette Meteorite. It weighs some 32,000 pounds. You can get an idea of its size from the two people in the picture. The meteorite is located in the Rose Center of the American Natural History Museum in New York City. (Photo: GreenGimmick, Photobucket)

    The light curve of UCAC4 248-108672 during Chariklo’s occultation on 3 June 2013. The light curve shows the stellar light as a function of time, with the central dip caused by Chariklo transiting in front of the background star, and the two dips either side due to Chariklo’s two rings blocking some of the stellar light.
