What happens to planet-sized objects that don’t have a star? A team of astronomers studying Jupiter-mass binary objects (JuMBOs) in the Orion Nebula are gaining a new understanding of these unusual systems.
A new study may help settle the question of how rapidly the Milky Way’s supermassive black hole is spinning.
The Atacama Large Millimeter/submillimeter Array (ALMA) has just received a “heart transplant,” high in the Atacama Desert in Northern Chile. ALMA, the most complex astronomical observatory ever built on Earth, installed a new hydrogen maser. Funded by the National Radio Astronomy Observatory (NRAO), this upgrade marks an essential investment, setting a new standard in reliability for observations.
Following a generous grant from the Heising-Simons Foundation, the Central Development Laboratory (CDL) at the National Science Foundation’s (NSF) National Radio Astronomy Observatory (NRAO) has selected their first recipient of the postdoctoral Women in Engineering fellowship, Priyanka Mondal. The Women in Engineering program increases opportunities for women to enter the field of radio astronomy through engineering pathways.
The Event Horizon Telescope (EHT) Collaboration has released new images of supermassive black hole M87*. A recent paper published in the journal Astronomy & Astrophysics presents new images from data collected by the Atacama Large Millimeter/submillimeter Array (ALMA) and several other instruments within the EHT. These new images show a bright ring surrounding a deep central depression, “the shadow of the black hole,” as predicted by general relativity. Excitingly, the brightness peak of the ring has shifted by about 30º compared to the first images, which is consistent with scientists’ theoretical understanding of variability from turbulent material around black holes.
An international team of astronomers have found ring and spiral structures in very young planetary disks, demonstrating that planet formation may begin much earlier than once thought. The results were presented today at the 243rd Meeting of the American Astronomical Society.
