May's Blue Moon wows stargazers worldwide — see these stunning photos of the smallest full moon of 2026

• NASA activated the Nancy Grace Roman Space Telescope's 300-megapixel camera for the first time this week to capture a debut test image. • The first image features stars appearing neon-green as part of the initial technical verification of the telescope's powerful imaging system.

• NASA scientists and industry partners recently field-tested an artificial intelligence application using a fleet of three robots to simulate an independent science team. • The test assessed the robots' ability to work together autonomously to increase the efficiency of solar system exploration.

• Researchers discovered that regular physical activity triggers epigenetic reprogramming, which is a process that changes how genes are expressed without altering the DNA sequence. • The study found that exercise preactivates natural killer cells and CD8+ T cells to more effectively identify and destroy abnormal cells.

• The peer review system in the U.S science grant process is being dismantled, which has taken eighty years to build and establish. • The people leaving the system now have taken decades to train, resulting in significant losses of expertise and potential discoveries.

• Researchers are exploring cutting-edge discoveries that shape our understanding of the universe through scientific innovation and technological advancement. • New revelations in modern physics and engineering emerge almost daily as a result of ongoing research.

• Many household smoke alarms use americium, a radioactive element created in nuclear reactors, to detect smoke. • These devices typically contain about 0.3 micrograms of the element and can be purchased for around ten dollars.

• Russia's Progress 96 spacecraft docked with the International Space Station on September 19. • The freighter delivered 3 tons of cargo and supplies to the orbiting laboratory at 9:44 a.m. ET.

• Researchers developed the first 3D map of an ovary to study how and when oocytes, which are immature eggs, are activated. • The study findings were published in the journal Nature Aging.

• In 1922, Howard Carter discovered the entrance to Tutankhamun's tomb, a significant discovery in Egyptian archaeology. • The tomb's discovery has led to a renewed search for Queen Nefertiti, with some believing she may be buried in secret chambers within King Tut's tomb.

• Researchers discovered a 9-million-year-old capybara tooth in Chile's Atacama Desert. • The presence of this semi-aquatic rodent suggests the region had unexpectedly wet conditions during that era.

• Astronomer Stephen Kane created computer models to simulate the possibility of Venus having a moon that it pulled back towards itself, tore apart, and consumed. • Kane's models included different masses of hypothetical moons and varied spin speeds of Venus to predict various outcomes, according to his research.

• Scientists discovered 27 mysterious frozen objects orbiting in the far reaches of the solar system beyond Neptune. • These tiny worlds are located in the distant outer regions of the solar system.
