Disk Detective is the first NASA-led and funded-collaboration project with Zooniverse. It is NASA's largest crowdsourcing citizen science project aiming at engaging the general public in search of stars, which are surrounded by dust-rich circumstellar disks, where planets usually dwell and are formed.
M33 X-7 is a black hole binary system in the Triangulum Galaxy.The system is made up of a stellar-mass black hole and a companion star. The black hole in M33 X-7 has an estimated mass of 15.65 times that of the Sun (M ☉) (formerly the largest known stellar black hole, though this has now been superseded amongst electromagnetically-observed black holes by an increased mass estimate for Cygnus ...
Stellar structure. Cross-section of the Sun. Stellar structure models describe the internal structure of a star in detail and make predictions about the luminosity, the color and the future evolution of the star. Different classes and ages of stars have different internal structures, reflecting their elemental makeup and energy transport ...

Stellar classification. In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines.
The primary scientific driver of SpeX was to provide maximum simultaneous wavelength coverage at a spectral resolving power which is well-matched to many planetary, stellar and galactic features, and at resolving power which adequately separates sky emission lines and disperses sky continuum.
Theoretical work in 1996 placed the limit at approximately 1.5 to 3.0 M ☉, corresponding to an original stellar mass of 15 to 20 M ☉; additional work in the same year gave a more precise range of 2.2 to 2.9 M ☉.
