Astronomers Finally Find Milky Way’s Missing Black Hole Wind

This image shows the evidence for the wind blowing away from Sagittarius A*: the white dot in the center of the image shows the supermassive black hole; in orange is data from ALMA, mapping the location of cold gas composed of carbon monoxide in the image; in blue is X-ray data from Chandra; a large cone-shaped cavity, visible as an absence of cold gas in the ALMA data, is filled by hot X-ray-emitting gas in the Chandra data.

After a 50-year search, astronomers have uncovered evidence that Sagittarius A* -- the 4.3-million-solar-mass black hole that resides at the center of our Milky Way Galaxy -- is blowing a hot cosmic wind into its surroundings, carving out a giant cavity near the Galaxy’s heart.

June 8, 1625: The birth of Giovanni Cassini

Giovanni Cassini was born in Perinaldo, in what is now Italy, on June 8, 1625. Early work on Jupiter and Mars’ rotational periods and the positions of Jupiter’s satellites led to an invitation to Paris and the Academie des Sciences by King Louis XIV; he became director of the Observatorie de Paris in 1671, andContinue reading "June 8, 1625: The birth of Giovanni Cassini"

Magnetic Fields May Solve a Longstanding Binary Star Mystery

Gas Flows Around Binary Protostar System VisualizationMagnetic fields may be the hidden force bringing both newborn stars and giant black holes together. New computer simulations suggest that magnetic fields play a crucial role in helping pairs of young stars form. The findings could explain why binary star systems are so common throughout the Milky Way and may even offer clues about [...]
