To the surprise of many planetary scientists, the oxidized iron mineral hematite has been discovered at high latitudes on the Moon. That’s according to a study published in Science Advances led by Shuai Li, an assistant researcher at the Hawai‘i Institute of Geophysics and Planetology (HIGP) in the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST). Iron ...
Computer simulations are showing astrophysicists how massive clumps of gas within galaxies scatter some stars from their orbits, eventually creating the smooth, exponential fade in the brightness of many disk galaxies. Researchers from Iowa State University, the University of Wisconsin-Madison, and IBM Research have advanced studies they started nearly 10 years ago. They originally focused ...
Dark matter is the invisible glue that keeps stars, dust, and gas together in a galaxy. This mysterious substance makes up the bulk of a galaxy’s mass and forms the foundation of our Universe’s large-scale structure. Because dark matter does not emit, absorb, or reflect light, its presence is only known through its gravitational pull ...
Recent science missions and results are bringing the search for life closer to home. Scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Florida Institute of Technology (FIT) may have figured out how to determine whether life on Mars, the Moon, and other rocky objects in the universe is — or ...
As missions like NASA’s Hubble Space Telescope, TESS, and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited. In a new study published recently in The Planetary Science Journal, a ...
This latest image of Jupiter’s storms, taken by NASA’s Hubble Space Telescope on Aug. 25, 2020, was captured when the planet was 406 million miles from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm brewing, and a cousin of the famous ...
Astronomers using the National Science Foundation’s Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy — a measurement that could help determine if they are the sources of the long-mysterious Fast Radio Bursts (FRBs). Magnetars are a variety of neutron stars ...
When stars like our Sun die, all that remains is an exposed core — a white dwarf. A planet orbiting a white dwarf presents a promising opportunity to determine if life can survive the death of its star, according to Cornell researchers. In a study published in the Astrophysical Journal Letters, they show how NASA’s ...
CU Boulder and Lockheed Martin will lead a new space mission to capture the first-ever closeup look at a mysterious class of solar system objects: binary asteroids. These bodies are pairs of asteroids that orbit around each other in space, much like the Earth and Moon. In a project review on Sept. 3, NASA gave ...
New composite images made by NASA’s Cassini spacecraft are the most detailed global infrared views ever produced of Saturn’s moon Enceladus. And data used to build those images provides strong evidence that the northern hemisphere of the moon has been resurfaced with ice from its interior. Cassini’s Visible and Infrared Mapping Spectrometer (VIMS) collected light ...
