'Yoyo stars' found responsible for off-center cosmic bubbles

Astronomers have developed a new model to simulate the formation of a cluster of baby stars. Comparison with the well-known real case of the Orion Nebula shows that its off-center bubble of ionized gas was caused by a massive ...

European astronomers discover four new brown dwarfs

Astronomers from the Astronomical Observatory of Padova, Italy, and elsewhere have conducted observations of 25 stars as part of the COPAINS Pilot Survey. As a result, they detected four new brown dwarfs that received designations ...

Hubble's double take on a spiral galaxy

The magnificent spiral galaxy M99 fills the frame in this image from the NASA/ESA Hubble Space Telescope. M99—which lies roughly 42 million light-years from Earth in the constellation Coma Berenices—is a "grand design" ...

Planet-forming disks evolve in surprisingly similar ways

A group of astronomers, led by Sierk van Terwisga from the Max Planck Institute for Astronomy, have analyzed the mass distribution of over 870 planet-forming disks in the Orion A cloud. By exploiting the statistical properties ...

Image: Hubble snaps yet another spiral galaxy

The spiral galaxy M91 fills the frame of this Wide Field Camera 3 observation from the NASA/ESA Hubble Space Telescope. M91 lies approximately 55 million light-years from Earth in the constellation Coma Berenices and—as ...

Webb telescope's cool view on how stars, planets form

The ongoing success of the multi-instrument optics alignment for NASA's Webb telescope's near-infrared instruments has moved the attention of the commissioning team to chill as we carefully monitor the cooling of the Mid-InfraRed ...

Image: Hubble views an infant star's outburst

An energetic outburst from an infant star streaks across this image from the NASA/ESA Hubble Space Telescope. This stellar tantrum—produced by an extremely young star in the earliest phase of formation—consists of an ...
