LPL Spotlight Stories

A new study reporting the discovery of an asteroid impact crater buried under the seafloor off the coast of Africa lends support to the idea that more than one asteroid may have impacted Earth at the time the dinosaurs went extinct.

More Than One Asteroid Could Have Spelled Doom for the Dinosaur

A newly discovered impact crater below the seafloor hints at the possibility that more than one asteroid hit Earth during the time when dinosaurs went extinct.

As Reflective Satellites Fill the Skies, UArizona Students Are Making Sure Astronomers Can Adapt

University of Arizona students have completed the first comprehensive brightness study to characterize mega-constellation satellites cluttering the skies.
RAVEN combines rovers and drones to explore landscapes that may otherwise be inaccessible

Project RAVEN, Summer 2022

Associate Professor Christopher Hamilton is again in Iceland this summer, leading a team in support of his RAVEN project. RAVEN combines rovers and drones to explore landscapes that may otherwise be inaccessible, such as young volcanic terrains on Mars that are too rough for a rover to traverse.

 This landscape of what looks like mountains and valleys speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA's Webb Telescope, this image reveals for the first time previously invisible areas of star birth. NASA, ESA, CSA, and STScI

Webb Telescope's Stunning First Images Made Possible by UArizona Instruments and Expertise

The highly anticipated observations mark just the beginning of many years of new science and discovery, and University of Arizona experts are at the helm.

OSIRIS-REx Scientists: Taking Asteroid Sample Was Like Punching a Ball Pit

Before-and-after images and measurements revealed a treasure trove of data from the few seconds that it took for the OSIRIS-REx spacecraft to collect an asteroid sample, which is currently en route to Earth.

 In this picture of the Spirograph Nebula, a dying star about 2,000 light-years from Earth, NASA's Hubble Space Telescope revealed some remarkable textures weaving through the star's envelope of dust and gas. UArizona researchers have now found evidence that complex carbon nanotubes could be forged in such environments.NASA and The Hubble Heritage Team (STScI/AURA)

Dying stars could seed interstellar medium with carbon nanotubes

Evidence suggests that carbon nanotubes, tiny tubes consisting of pure carbon, could be forged in the envelopes of dust and gas surrounding dying stars. The findings propose a simple, yet elegant mechanism for the formation and survival of complex carbon molecules in space.

How to Spot Asteroids

“Stay up all night,” says Gregory Leonard, a research scientist at the University of Arizona’s Catalina Sky Survey, who uses a network of powerful telescopes to find and track what NASA calls near-Earth objects, including asteroids that come within 120 million miles of the sun. Go looking in a place without light pollution on a cloudless night with a steady atmosphere. Avoid a full moon.

Dr. Sarah Moran Named UArizona Sursum Fellow

Dr. Moran was selected for her proposal on Haze Evolution in sub-Neptune Exoplanets through UV Laboratory Experiments.

Dr. Sukrit Ranjan Joins LPL Faculty Starting Fall 2022

Sukrit's work is focused on the origin of life on Earth, the search for life on other worlds, and the atmospheres of rocky exoplanets. He applies photochemistry to questions related to the origin of life on Earth and the search for life on other worlds.
