Cygnus X-1’s ‘Dancing’ Jets Measured at Half the Speed of Light

Astronomers measured the jets of Cygnus X-1 by mapping their wobble.
The outflows were found to travel at about half the speed of light.
Stellar winds from the black hole’s companion star helped reveal the jets’ motion.

Starquake Models Tie White Dwarf Magnetism to Hidden Fields Inside Stars

New models connect white dwarf surface magnetism to interior magnetic evidence from starquakes.
The work supports the idea that some stellar magnetism is preserved over long evolutionary timescales.
The result gives astronomers a framework to relate magnetic fields in living stars to those in stellar remnants.

Moon phase today explained: What the Moon will look like on April 14, 2026

The Moon is down to a thin waning crescent as the current lunar cycle closes

The Moon is in a waning crescent phase on April 14, 2026.
Only 13% of the lunar disk is illuminated, according to NASA's Daily Moon Guide.
Very little surface detail is visible, with the Grimaldi Basin noted as the main feature.
The next Full Moon is expected on May 1, 2026.

Hubble Captures a Spiral Galaxy Powered by a Hungry Black Hole

NASA released a new Hubble image of barred spiral galaxy IC 486.
The galaxy sits about 380 million light-years away and shows both old and young stellar regions.
Its bright center is powered by an active galactic nucleus around a supermassive black hole.

ALMA Spots Giant Gas Ring Around a Young Protostar, Offering New Clues to Star Formation

ALMA Band 9 observations revealed a warm gas ring about 1,000 astronomical units across around MC 27.
Researchers link the structure to magnetic flux associated with the protostar’s disk.
The finding may help explain how young stars release excess energy and continue accreting mass.

This artist's illustration shows the gas giant TOI-5205 b orbiting its M-dwarf (red dwarf) star. Astronomers expect to find massive gas giants around more massive stars than this, so this arrangement is a puzzle. It's not the only gas giant around a low-mass star, and collectively, they challenge astronomers' understanding of planet formation. Image Credit: Katherine Cain, Carnegie Science.

A Giant Planet Around a Tiny Star Is Testing Theories of How Worlds Form

TOI-5205b is a roughly Jupiter-mass planet orbiting a low-mass M-dwarf every 1.6 days.
Its size and host-star mass strain standard disk-scaling expectations in planet formation theory.
Researchers are now studying similar systems with JWST through the GEMS program.

Young Jupiter’s Magnetic Environment May Explain Why It Has More Large Moons Than Saturn

Researchers modeled young Jupiter and Saturn and their circumplanetary disks.
The study links moon-system differences to magnetic accretion and a magnetospheric cavity.
The model helps explain why Jupiter formed four large moons while Saturn is dominated by Titan.

Ancient Star Found in the Milky Way May Have Arrived From Another Galaxy

A student team found an extremely metal-poor star using Sloan Digital Sky Survey data.
The star may be one of the oldest known and likely formed outside the Milky Way.
The discovery connects early stellar chemistry with the Milky Way’s merger history.

AI sifts TESS observations and helps validate more than 100 new exoplanets

Researchers used the RAVEN machine-learning pipeline on TESS data covering more than 2 million stars.
The study reports over 100 newly validated exoplanets and more than 2,000 vetted candidates.
The work highlights how AI can help manage false positives and extract more science from large survey archives.

Survey of exoplanet spins backs long-predicted link between mass and rotation

Researchers used Keck Observatory data and prior measurements to compare spin across exoplanets and brown dwarfs.
The survey supports a long-predicted relationship between mass and rotation.
Gas giant planets were found to spin faster than more massive brown dwarf counterparts after accounting for mass, size, and age.
Scientists say spin can preserve clues about how distant worlds formed.

Astronomers studied more than 1 million galaxies and more than 8,000 growing supermassive black holes (SMBH) over billions of years to try to answer a difficult question. During Cosmic Noon about 10 billion years ago, the growth of SMBH began to slow dramatically. The image on the left represents one of the rapidly-growing SMBH in the past, and the image on the right represents a slower-growing SMBH about 3 billion light-years away.

Astronomers Trace the Long Slowdown in Supermassive Black Hole Growth

Researchers studied more than 1 million galaxies and over 8,000 growing supermassive black holes.
The study says black hole growth peaked around z ≈ 1.5 to 2 and then declined.
A leading explanation is the reduced availability of cold gas needed for accretion.
