points the way 3o north to the planetary nebula NGC 6309.
Workshop on RS Ophiuchi
and the Recurrent Nova Phenomenon (2006: Keele, UK) Ed.
The observations focused on a system called RS Ophiuchi
, which is actually a pair of stars 5,000 light-years from Earth.
18 RS Ophiuchi
has excited scientists because it appears to be on the brink of becoming what?
Let's start by looking toward the inner regions of the Milky Way at one of the most colorful and photogenic targets: the Rho Ophiuchi
95') Regulus near the Moon (09h) Mercury between the Sun and Earth (22h) 19 Spica (18h) and Mars (23h) near the Moon 21 Moon occults Saturn (21h) 22 Last Quarter Moon (19h) Moon occults chi Ophiuchi
(22h) 23 Neptune at conjunction (20h) 24 Moon furthest south (-19.
In the stellar nursery near the star Rho Ophiuchi
, located in the constellation Ophiuchus, researchers from the Niels Bohr Institute at the University of Copenhagen detected signatures of the simplest possible sugar in nature, glycolaldehyde.
NASA's Spitzer Space Telescope, a space-based infrared observatory, spotted the buckyballs around the double-star system XX Ophiuchi
Path was from alpha Ophiuchi
, passed 109 Herculis and toward alpha Lyrae (15[degrees] to 20[degrees]).
Sprawling and mostly dim, Ophiuchus has a fairly bright, 2nd-magnitude head--Alpha (a) Ophiuchi
, also known as Rasalhague.
Some 300 young stars shine through the dust in this infrared portrait of the main cloud of a nearby star-forming region called Rho Ophiuchi
The recurrent nova RS Ophiuchi
(RS Oph) has previously reached this level of brightness five times in the last 108 years, most recently in 1985.
