Astronomers from the Queen's University in Kingston, Canada and elsewhere, have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a mysterious source known as VLA 1623 West. Results of the study, published ...
The Flame Nebula or NGC 2024 is a large star-forming region in the constellation Orion that lies about 1,400 light-years from Earth. Hubble studied this nebula to look for protoplanetary disks, or "proplyds"—disks of gas ...

(Phys.org)—A dwarf transitional protoplanetary disk was found around the young star XZ Tau B, located some 460 light years away. According to a research paper published online on June 9 on arXiv.org, this disk of dust is ...
The dusty disk surrounding the star TW Hydrae exhibits circular features that may signal the formation of protoplanets. LMU astrophysicist Barbara Ercolano argues, however, that the innermost actually points to the impending ...
