The subject of today’s NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more than 150 globular clusters in our galaxy, though there may […]
In May 2024, auroras were observed at unusually low latitudes across the globe, lighting up skies that rarely see such displays. Inside Earth’s magnetosphere, the region of space surrounding our planet and dominated by its intrinsic magnetic field, something significant was finally observed.

How do you teach someone to look at the moon? Not glance at it, the way we all have on a clear night, but truly read it, the way a geologist reads a hillside. That was the challenge NASA set itself before Artemis II, because when Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen […]
Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute challenge for extremely precise technologies, such as lasers and semiconductor manufacturing equipment, where even minute dimensional changes can compromise precision.

An international team of astronomers has used the James Webb Space Telescope (JWST) and a natural phenomenon known as gravitational lensing to achieve a definitive characterization of LAP1-B, an ultra-faint galaxy from 13 billion years ago. Expanding upon initial detections, this new study revealed a record-breaking low oxygen abundance—merely 1/240th that of the sun.

Astronomers from Germany and Turkey have analyzed available data from various space telescopes to investigate an ultraluminous X-ray source designated X-4, which is located in the nearby galaxy NGC 4631. Results of the new study, published June 22 on the preprint server arXiv, yield important insights into the spectral and timing variability of this source. […]
Physicists at Paderborn University have, for the first time, experimentally demonstrated the so-called “return” of Rabi oscillations in semiconductor quantum dots. The phenomenon, which was first predicted theoretically in 2007, describes the decrease in the emission intensity of the quantum dots, which are initially damped by interactions with the lattice vibrations of a solid (phonons). […]
WAR.GOV/UFO, the Pentagon’s PURSUE portal, launched on May 8, 2026 and has already passed 1.7 billion hits, making it one of the most visited US government sites ever.

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied explanation. Astronomers have proposed various competing theories to account for these stars, but none has been […]

The NASA Artemis program, now supported by 67 countries under the Artemis Accords, plans to return humans to the moon by 2028. A recent White House Executive Order has gone further, directing NASA to establish a permanent lunar outpost by 2030.

Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit more complex vibrational and rotational dynamics that make them more difficult to cool and trap.
