A University of Pretoria-led team used MeerKAT and gravitational lensing to discover the most distant hydroxyl megamaser ever found, pushing the category into new territory they're calling a "gigamaser."

HATLAS J142935.3-002836 sits over 8 billion light-years away, with its 18-centimeter radio waves amplified by a foreground galaxy to become the most luminous ever detected at this distance.

The discovery hands astronomers a powerful beacon for studying galaxy collisions and starbursts in the early universe, while showcasing just how capable MeerKAT has become as a radio telescope.

Using data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton, astronomers identified a possible supernova remnant hiding inside a star-forming region close to the center of the Milky Way.

The X-ray blob sits 26,000 light-years away in Sagittarius C, expanding at two million miles per hour and estimated to be at least 1,700 years old based on current models.

If confirmed, this would be one of the closest supernova remnants to our galaxy's supermassive black hole, reshaping what we know about how elements for life are seeded near the galactic core.

Elon Musk's SpaceX officially began trading on Wall Street, marking the close of the largest initial public offering in history and a huge milestone for the private space industry.

The IPO raised at least $75 billion and valued SpaceX at nearly $1.8 trillion, with early trading showing a 25% jump from its $135 debut price under the ticker "SPCX."

The capital fuels Musk's long-term plan to get humanity to Mars and weave space infrastructure together with AI, putting serious money behind what has long been an ambitious vision.

The University of Iowa-led NASA TRACERS mission published its first results, showing in detail how solar energy interacts with Earth's magnetic field and what that means for space weather forecasting.

Twin satellites measured electron velocities and concentrations across 149 encounters in low-Earth orbit cusps, with 57 showing characteristic dispersion signatures at the equatorward edge of the polar cusp region.

The measurements map solar energy's complete path from magnetic reconnection all the way to Earth's ionosphere, revealing fine-scale variations in how efficiently the Sun and Earth exchange energy.

NASA's Hubble and James Webb Space Telescopes joined forces to produce a striking composite image of Messier 64, the galaxy famously nicknamed the Black Eye for its dramatic dark dust band.

The image blends Webb's near- and mid-infrared data with Hubble's ultraviolet and visible observations, catching the galaxy's gas rotating in the opposite direction from its stars in remarkable detail.

That counterrotating structure is strong evidence of an ancient merger with a satellite galaxy over a billion years ago, and the Black Eye is still working through the aftermath today.
