Image: Hubble snags starry galaxy

In this image taken by the Hubble Space Telescope, the galaxy NGC 4380 looks like a special effect straight out of a science fiction or fantasy film, swirling like a gaping portal to another dimension.

The clumpy and lumpy death of a star

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this "new star" was far beyond ...

Spiral arms in a young accretion disk around a baby star

An international research team, led by Chin-Fei Lee at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has detected a pair of spiral arms in an accretion disk around a protostar (baby star), using ...

Data milestone achieved in variable star repository

Compiling together multiple pieces of information for each of a million-plus objects is no easy or quick task, but that is exactly what Sebastián Otero, Patrick Wils, Patrick Schmeer, and Klaus Bernhard did. Due to this ...

SUPERB survey detects new slowly-spinning radio pulsar

Astronomers have detected a new slowly rotating radio pulsar as part of the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB). The newly found object, designated PSR J2251−3711, turns out to be one of the slowest ...

Gas 'waterfalls' reveal infant planets around young star

The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made with the Atacama Large ...

Heron survey fishes out detail in ghostly galaxy outskirts

Astronomers have completed the largest survey to date of the faint outskirts of nearby galaxies, successfully testing a low-cost system for exploring these local stellar systems. R. Michael Rich of the University of California, ...

Going against the flow around a supermassive black hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) to study this ...

Image: Foreground asteroid passing the Crab Nebula

When astronomers use the NASA/ESA Hubble Space Telescope to study the deep sky, asteroids from our solar system can leave their marks on the captured pictures of far-away galaxies or nebulae. But rather than be annoyed at ...

2I/Borisov: Interstellar comet with a familiar look

A new comet discovered by amateur astronomer Gennady Borisov is an outcast from another star system, yet its properties are surprisingly familiar, a new study led by Jagiellonian University researchers shows. The team's findings ...

Astronomers use giant galaxy cluster as X-ray magnifying lens

Astronomers at MIT and elsewhere have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very first, ...

Hubble snaps spiral's profile

The NASA/ESA Hubble Space Telescope sees galaxies of all shapes, sizes, luminosities and orientations in the cosmos. Sometimes, the telescope gazes at a galaxy oriented sideways—as shown here. The spiral galaxy featured ...

Open cluster ASCC 123 investigated in detail

Using the Galileo National Telescope, astronomers have conducted a high-resolution spectroscopic study of the open cluster ASCC 123 as part of the Stellar Population Astrophysics (SPA) project. Results of the new research, ...

The nature of obscured active galactic nuclei

Most galaxies host a supermassive black hole (SMBH) at their nucleus, one whose mass exceeds a million solar-masses. When material actively accretes onto the SMBH, associated processes can produce an active galactic nucleus ...
