Data from NASA's New Horizons mission are providing new insights into how planets and planetesimals -- the building blocks of the planets -- were formed. The New Horizons spacecraft flew past the ancient Kuiper Belt object Arrokoth (2014 MU69) on... Continue Reading →
The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Southwest Research Institute scientists modeled the mixing of materials associated... Continue Reading →
The Trifid Nebula, also known as Messier 20, is easy to find with a small telescope. About 30 light-years across and 5,500 light-years distant it's a popular stop for cosmic tourists in the nebula rich constellation Sagittarius. As its name suggests, visible light pictures show...

A person's normal resting heart rate is fairly consistent over time, but may vary from others' by up to 70 beats per minute, according to analysis of the largest dataset of daily resting heart rate ever collected. Giorgio Quer of... Continue Reading →
Causes of cancer are being catalogued by a huge international study revealing the genetic fingerprints of DNA-damaging processes that drive cancer development. Researchers from the Wellcome Sanger Institute, Duke-NUS Medical School Singapore, University of California San Diego School of Medicine,... Continue Reading →
A "beating heart" of frozen nitrogen controls Pluto's winds and may give rise to features on its surface, according to a new study. Pluto's famous heart-shaped structure, named Tombaugh Regio, quickly became famous after NASA's New Horizons mission captured footage... Continue Reading →
Michigan State University and Stanford University scientists have invented a nanoparticle that eats away -- from the inside out -- portions of plaques that cause heart attacks. Bryan Smith, associate professor of biomedical engineering at MSU, and a team of... Continue Reading →
A new spacecraft is journeying to the Sun to snap the first pictures of the Sun’s north and south poles. Solar Orbiter, a collaboration between the European Space Agency, or ESA, and NASA, will have its first opportunity to launch... Continue Reading →
First images from the National Science Foundation's Daniel K. Inouye Solar Telescope reveal unprecedented detail of the sun's surface and preview the world-class products to come from this preeminent 4-meter solar telescope. NSF's Inouye Solar Telescope, on the summit of... Continue Reading →
