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

An artist's impression of a fast radio burst (FRB) arriving at Earth. The colors represent the burst arriving at different radio wavelengths, with long wavelengths (red) arriving several seconds after short wavelengths (blue). This delay is called dispersion and occurs when radio waves travel through cosmic plasma. Credit: Credit: Jingchuan Yu, Beijing Planetarium. For more

Starmus, already recognized as the most ambitious science and music festival in the world, returns to the Canary Islands in April 2025 as one of the great bets for the recovery of the island of La Palma. In collaboration with the Starlight Foundation and with the support of the IAC, “Starmus La
