Back to list of articles The starburst galaxy is packed with newborn stars fueled by its collision with at least two other galaxies. NGC 4449 as seen by the Gemini North telescope. The red regions indicate where there is ionized hydrogen in the galaxy, a sign of star formation. Credit: Gemini International Observatory/NOIRLab/NSF/AURA On June
Return to article list The Curiosity rover continues to conduct experiments, drilling more than 40 holes in Mars to help us better understand the Red Planet. The drill aboard the Curiosity rover created the hole in a rock that researchers call Mammoth Lakes. The bright spot to the left of the hole is where the
Return to article list The infrared telescope revealed a cluster of protostellar flows in the star-forming region, shedding new light on star formation. JWST found a cluster of aligned protostar outflows, visible at top left, in the Serpens Nebula. Credit: NASA, ESA, CSA, K. Pontoppidan (NASA Jet Propulsion Laboratory) and J.

The Vera C. Rubin Observatory at dawn. Credit: Vera C. Rubin Observatory/NOIRLab/AURA/NSF/J. Sources When the Vera C. Rubin Observatory comes online, perhaps at full capacity in 2025, this powerful and unique survey telescope, at high altitude in Chile, will study the skies in a new and unprecedented way. Originally called the Large Synoptic Survey Telescope,
A diagram of a perovskite solar cell. Credit: Ahmad Kirmani using Blender. The space environment is harsh and full of extreme radiation. Scientists who design spacecraft and satellites need materials that can withstand these conditions. in a article published in January 2024, my team of materials researchers showed that a next generation semiconductor material called
Return to article list Psyche has a nearly circular orbit in the asteroid belt, so it is unlikely to have come close to Earth. The metallic asteroid Psyche, shown in this artist's concept, may be the exposed iron-nickel core, or a fragment of one, of a larger object in the early stages of the solar
Return to article list The renewed energy flowing from an active galaxy provides astronomers with a high-energy mystery to explore in detail at multiple wavelengths. This artist's impression shows two stages in the formation of a disk of gas and dust around the enormous black hole at the center of the galaxy SDSS1335+0728. The core
A composite image showing the Full Moons in 2020 and 2021 by month. Credit: Soumyadeep Mukherjee. The Full Moon phenomenon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures that the entire side of the Moon facing us shines in the sunlight. Thanks to the Moon's orbit
Return to article list A peculiar white rock seems strangely out of place on the Red Planet. A closer look at the rock the Perseverance rover spotted on Mars. This is an improved version of mosaic, intended to improve visual contrast and accentuate color differences. Credit: NASA. NASA's Perseverance rover, which has been on Mars
