When the cloudy object G2 passed around Sagittarius A* in 2014, astronomers predicted it would look like this: flare lighting up the core of the galaxy. That didn't happen. New simulations explain what influences what happens when a star gets close to a supermassive black hole. Courtesy: ESO/S.Gillessen/MPE/Marc Schartmann.

New Simulations Show How a Star’s Destruction Could Make a Hidden Black Hole Light Up a Galaxy

New simulations examine how stellar destruction near supermassive black holes produces flares.
Tidal disruption events can briefly outshine their host galaxies.
The work helps explain why G2’s 2014 passage by Sagittarius A* did not produce the expected display.

Put nuclear reactors in space within a few years, White House tells Pentagon

White House Push for Space Reactors Sets an Aggressive Clock for Pentagon and NASA

A White House memo calls for reactors in orbit as early as 2028 and on the Moon as early as 2030.
The Pentagon has 90 days to brief top officials on use cases, payloads and mission planning.
Military demand for persistent power in space is a major source of urgency behind the policy.

Not Even the Largest Cosmic Objects Can Escape Newton and Einstein, Study Finds

A gravity test at cosmic scale adds weight to the dark matter picture

The article says a large new study found cosmic-scale observations remain consistent with standard gravity.
That weakens explanations based solely on modifying gravity at large scales.
The result strengthens the indirect case for dark matter without directly detecting it.

Blue Origin tests refurbished New Glenn booster ahead of possible Sunday launch

Blue Origin tests refurbished New Glenn booster ahead of possible Sunday launch

Blue Origin fired the seven BE-4 engines on its first previously flown New Glenn booster for about 20 seconds on April 16, 2026.
The rocket could launch AST SpaceMobile’s BlueBird-7 satellite as soon as Sunday, April 19, 2026, pending data review.
Blue Origin replaced the booster’s engines for this flight, showing it is still refining how New Glenn reuse will work in practice.

Artemis 2 is a benchmark in our space exploration program — and it depends on steady NASA funding

After Artemis 2, the Real Question Is Whether NASA Can Afford Its Ambitions

The commentary says Artemis 2 has been successfully completed.
It highlights a proposed 25 percent cut to NASA and nearly 50 percent cut to NASA science.
The argument is that human exploration needs steady funding to support science, inspiration and international standing.

Why Light Slows Down in Matter, and Why That Makes a ‘Light Boom’ Possible

Universe Today’s latest Cherenkov series installment focuses on why light slows in matter.
The explainer ties Maxwell’s equations to refractive index and medium-dependent light speed.
Examples include air, water, glass, diamond, and ultracold laboratory systems.
The slowed speed of light in a medium is what makes Cherenkov radiation possible.

James Webb Observations Sharpen the Debate Over How Supergiant Planets Form

Astronomers used Webb to study 29 Cygni b, a gas giant about 15 times Jupiter’s mass.
The planet’s heavy-element enrichment may help test competing theories of giant-planet formation.
The research could help clarify the boundary between massive planets and star-like bodies.

Contours of the James Bay Lowlands

James Bay’s Rising Shoreline Shows How Ice Age Forces Still Shape Earth Today

NASA highlighted beach ridges and frozen channels in the James Bay Lowlands from an ISS photograph.
The land around southern Hudson Bay is still rising by about 10 millimeters per year after glacial retreat.
The region is also one of the world’s largest peatland complexes, making it important for carbon storage.

Super Typhoon Sinlaku

Super Typhoon Sinlaku became a rare early-season Category 5-equivalent storm

NASA says Sinlaku reached around 280 km/h sustained winds as it neared the Marianas.
The storm is described as one of only a handful of Category 5 typhoons known to occur so early in the year.
Heavy rain began reaching Saipan, Tinian, and Rota on April 14.
Satellite imagery also captured gravity waves generated high above the storm.

Why the Weak Force’s Left-Handed Bias Still Shapes the Universe

The weak nuclear force is described as interacting only with left-handed particles.
The source ties beta decay to the conversion of a neutron into a proton via quark change.
Chien-Shiung Wu’s cobalt-60 experiments are presented as decisive evidence that left-right symmetry is broken in weak interactions.
