In May 2027, NASA's Nancy Grace Roman Space Telescope will launch to space. Appropriately named after the "Mother of Hubble," the telescope will use its 2.4-meter (7.9 ft) wide field of view primary mirror and advanced instruments to investigate the deeper mysteries of the cosmos. Roman will spend 75% of its observing time over its five-year primary mission conducting three core community surveys selected by the scientific community. Among them, Roman will conduct a High-Latitude Time-Domain Survey (HLTDS) to detect tens of thousands of type Ia supernovae.

Acting NASA administrator Sean Duffy says the agency will 'move aside' from climate sciences to focus on exploring moon and Mars
Acting NASA Administrator Sean Duffy says it's time for the agency to focus on the moon and Mars, not the "smorgasbord of priorities," like climate science, the agency has been directing its resources.
Pragmata rethinks sci-fi shooter combat, and it owes a lot to Snake (preview)
After five years, Pragmata could have been unambitious, but instead, it's a fascinating and innovative sci-fi game with heaps of potential.
South Korea's K-RadCube radiation satellite will hitch a ride on NASA's Artemis 2 moon mission
South Korea's K-RadCube satellite has arrived at NASA's Kennedy Space Center in Florida ahead of its launch toward the moon on the Artemis 2 mission next year.
Astronauts get stuffy noses in space because of microgravity, scientists find
Scientists are calling attention to an extremely common health problem that's been making astronauts uncomfortable: sinus issues.
Semiconductor wafer on ISS goes under the microscope | Space photo of the day for Aug. 20, 2025
This is part of a NASA-supported project hoping to fabricate "device-ready" wafers from space-grown crystals.
Iberian wildfires seen from space
Southern Europe is once again in the grip of extreme summer heat. Soaring temperatures and bone-dry land have fuelled widespread wildfires, with the Iberian Peninsula among the regions hardest hit. Flames continue to sweep across parched landscapes, as these images show.
Using Video Game Techniques To Optimze Solar Sails
Sometimes inspiration can strike from the most unexpected places. It can result in a cross-pollination between ideas commonly used in one field but applied to a completely different one. That might have been the case with a recent paper on lightsail design from researchers at the University of Nottingham that used techniques typically used in video games to develop a new and improved structure of a lightsail.

SpaceX partners with astronomers to protect radio astronomy from satellite interference
An automated system co-developed by SpaceX prevents disruption to radio astronomical observations caused by megaconstellations in low Earth orbit.
Tidal Forces and Orbital Evolution of Habitable Zone Planets
How do tidal forces determine a planet’s orbital evolution, specifically planets in the habitable zone? This is what a recently submitted study hopes to address as an international team of researchers investigated how tidal forces far more powerful than experienced on Earth could influence orbital evolution of habitable zone planets with highly eccentric orbits around low-mass stars. This study has the potential to help researchers better understand the formation and evolution of exoplanets, specifically regarding where we could find life beyond Earth.
The Milky Way's faintest satellite may not be what astronomers thought. 'These results solve a major mystery in astrophysics'
A distant galaxy nicknamed "Cosmic Grapes" is bursting with massive star-forming clumps — far more than expected — offering fresh clues about how galaxies grew in the early universe.
A Distant Star Explodes While Swallowing Its Black Hole Companion
Interactions between supernovae and black holes must be exceedingly rare. But that's the only explanation for a very strange explosion found with the Zwicky Transient Facility. In July 2023, the ZTF spotted strange light signals about 730 million light-years from Earth, and AI helped astronomers unravel what they were seeing.
