Astronomers just detected the biggest black hole jets ever seen—and named them Porphyrion

This picture taken by LOFAR shows Porphyrion, with the galaxy hosting the supermassive black hole in the centre. The largest blob-like structure near the centre is a separate smaller jet system. The relative size of our Milky Way galaxy is indicated in the lower-right corner. Credit: LOFAR Collaboration / Martijn Oei (Caltech) The largest known

Astronomers discover parallel disks and jets erupting from a pair of young stars

At left, a mid-infrared image of the rho Ophiuchi molecular cloud complex by NASA’s Spitzer Space Telescope, the focus pointing to star system WL20. At right, WL20 expands to reveal an artist’s impression of this new discovery. Astronomers couldn’t believe their luck when observations across multiple radio and infrared wavelengths from ALMA and JWST revealed

Astronomers analyze masses, orbital properties and atmospheric features of six exoplanets

A team of researchers led by astronomers at UCI has obtained highly precise information about six confirmed exoplanets orbiting TOI-1136, a dwarf star about 270 light years from Earth. Credit: Rae Holcomb / UCI A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers’ knowledge of planet formation and

Astronomers detect new pulsar wind nebula and its associated pulsar

Known Galactic SNRs are indicated by red circles (Green, 2019, 2022), while known Galactic HII regions

Astronomers capture formation of a powerful cosmic jet

While both images in a show brightness temperature (color scale), the image on the right also shows the recovered electric vector position angles overlaid as ticks. Their

Astronomers show magnetic field of a red dwarf star may be approaching polar reversal

Chastanet—Service communication OMP The 11-year solar activity cycle is a well-known phenomenon, during which the intensity of the sun’s magnetic field varies and its polarities reverse. Over the past 30 years, astronomers have identified similar behavior in several sun-like stars.

Astronomers shed new light on formation of mysterious fast radio bursts

Nearly all FRBs identified have originated

Astronomers puzzled by ‘planet that shouldn’t exist’

Credit: Julian Baum The search for planets outside our solar system—exoplanets—is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at least one planet per star in our galaxy. Many current research efforts aim
