ALMA captures stirred-up planet factory

Planet-forming environments can be much more complex and chaotic than previously expected. This is evidenced by a new image of the star RU Lup, made with the Atacama Large Millimeter/submillimeter Array (ALMA).

Image: Hubble snaps ghostly galaxy

A notable feature of most spiral galaxies is the multitude of arching spiral arms that seemingly spin out from the galaxy's center. In this image, taken with the NASA/ESA Hubble Space Telescope, the stunning silvery-blue ...

If you're looking for fireworks for the U.S. celebration of Independence Day, then look no further than the world of astronomy. The cosmic firework at the center of this image, the spiral galaxy NGC 925, resembles a vast ...

Image: Hubble spots feathered spiral

The spiral pattern shown by the galaxy in this image from the NASA/ESA Hubble Space Telescope is striking because of its delicate, feathery nature. These "flocculent" spiral arms indicate that the recent history of star formation ...

New method to study barred spiral galaxies

Analysis of gas motion in 20 nearby spiral galaxies has revealed a clear difference between those with bars and those without bars. This suggests that already available data on gas motion can be used to study bars in spiral ...

Image: Hubble spots stretching spiral

This sparkling spiral galaxy looks almost stretched across the sky in this new image from the NASA/ESA Hubble Space Telescope. Known as NGC 4100, the galaxy boasts a neat spiral structure and swirling arms speckled with the ...

Image: Hubble spots spirals within a spiral

At first glance, the subject of this NASA/ESA Hubble Space Telescope image looks to be a simple spiral galaxy, with two pinwheeling arms emerging from a central bar of stars and material that cuts through the galactic ...

Image: Hubble gazes at fluffy-looking galaxy

This image taken by the NASA/ESA Hubble Space Telescope shows the galaxy NGC 4237. Located about 60 million light-years from Earth in the constellation of Coma Berenices (Berenice's Hair), NGC 4237 is classified as a flocculent ...
