According to Bradley Schaefer (Louisiana State University), the 11th-magnitude variable star, V Sagittae, will outshine Sirius and maybe even Venus — despite its distance of some 7,500 light-years.
A new database from the American Association of Variable Star Observers enables astronomers (amateur and professional alike) to store data from any variable object in the sky.
Follow-up observations of an amateur-discovered exoplanet show that the planet orbits its star at the snow line, where ice giants may form.
The amateurs of the AAVSO monitored the star T Ursae Minoris for a century. Now, astronomers think they can explain the star's recent change in behavior.
Track satellites, spot flashes on the Moon, monitor violent stars — learn how amateur astronomers can become involved in professional science.
In a rare move, a sleepy cataclysmic variable blows its top and suddenly becomes a nova.
