constellation Boötes tagged posts

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes — that could be the first radio emission collected from a planet beyond our solar system.

The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de Paris — Paris Sciences et Lettres University and Jean-Mathias Griessmeier of the Université d’Orléans will publish their findings in the forthcoming research section of Astronomy & Astrophysics, on Dec. 16.

The foreground shows rocky asteroids; the red ring represents the rocky debris that remains of former asteroids or a minor planet that have already been broken apart by the strong gravity of the white dwarf.

Object in the constellation Boötes with C, H, O, N. Many scientists believe the Earth was dry when it first formed, and that the building blocks for life on our planet – carbon, nitrogen and water – appeared only later as a result of collisions with other objects in our solar system that had those elements...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that a dim, cool dwarf star is generating a surprisingly powerful magnetic field, one that rivals the most intense magnetic regions of our own Sun.

The star’s extraordinary magnetic field is potentially associated with a constant flurry of solar-flare-like eruptions...
