This frame from a movie shows the progression of NASA's Near-Earth Object Wide-field Survey Explorer (NEOWISE) investigation for the mission's first two years following its restart in December 2013. Green circles represent near-Earth objects.
These radar images of comet P/2016 BA14 were taken on March 22, 2016, by scientists using an antenna of NASA's Deep Space Network at Goldstone, CA. At the time, the comet was about 2.2 million miles (3.6 million kilometers) from Earth.

These first radar images of 2015 TB145 from the National Science Foundation's 1,000-foot (305-meter) Arecibo Observatory in Puerto Rico, indicate the near-Earth object is spherical in shape and approximately 2,000 feet (600 meters) in diameter.
Image of the southern polar regions of comet 67P/Churyumov-Gerasimenko taken by Rosetta's Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on September 29, 2014, when the comet was still experiencing the long southern winter.
Scientists from the European Space Agency's Rosetta team have honored two late team members by naming comet features after them. The comet is 67P/Churyumov-Gerasimenko, where the mission successfully landed a probe.
The asteroid Euphrosyne glides across a field of background stars in this time-lapse view from NASA's WISE spacecraft. Euphrosyne is quite dark in visible light, but glows brightly at infrared wavelengths.
Scientists using two giant, Earth-based radio telescopes bounced radar signals off passing asteroid 2011 UW158 to create images for an animation showing the rocky body's fast rotation. This is a frame from the animation.
Asteroid Named for Nobel Prize Winner Joins Historic Lineup
An asteroid discovered by NASA's NEOWISE spacecraft has been given the formal designation 316201 Malala, in honor of Malala Yousafzai of Pakistan, who received the Nobel Peace Prize in 2014. The asteroid's previous appellation was 2010 ML48.
This image shows Cornelia Crater on the large asteroid Vesta. On the right is an inset image showing an example of curved gullies, indicated by the short white arrows, and a fan-shaped deposit, indicated by long white arrows.
Finder Chart for Viewing Comet C/2014 Q2 (Lovejoy)
On clear nights in January 2015, comet C/2014 Q2 (Lovejoy) is visible in the Taurus region of the sky to observers using binoculars. This chart indicates where to look for it on different dates during the month.
Comet C/2014 Q2 (Lovejoy) is one of more than 32 comets imaged by NASA's NEOWISE mission from December 2013 to December 2014. This image of comet Lovejoy combines a series of observations made in November 2013.
