The paper was suggested by The flare ends with a sharp decay at a time that coincides with the transition to the spherical phase. "We fully expected this to be a spherical shell," says Arlin Crotts of Columbia University, a member of the research team. Long before Flamsteed fixed the beginning of Zodiac at 0 degree Aries, the Indian astronomer Brahmagupta fixed it at 0 degree Aswini ( Beta Arietis ). Aryabhatiya ends with spherical astronomy in Gola, where he applied plane trigonometry to spherical geometry by projecting points and lines on the surface of a sphere onto appropriate planes.

The paper selected for the fourth Astronomy Twitter Journal Club meeting (8:10 p.m. In 1950, Dutch astronomer Jan Oort proposed that certain comets come from extremely distant, spherical shell of icy bodies surrounding the solar system. The team used the space observatory to look at the light emitted by the close double-star system's orbital plane, instead of escaping the system. Lee Rannals for redOrbit.com – Your Universe Online Astronomers using NASA's Hubble Space Telescope have mapped out a 3D structure of material ejected from an exploding star. A marriage of the planisphere and dioptra, the astrolabe was effectively an analog calculator capable of working out several different kinds of problems in spherical astronomy. UT, Thursday 7th July 2011) was Relativistic shock breakouts – a variety of gamma-ray flares: from low luminosity gamma-ray bursts to type Ia supernovae by Nakar and Sari, June 13 2011 (arXiv:1106.2556v1).
