- Cannabis, also known as marijuana among other names, is a psychoactive drug from the cannabis plant. Native to Central or South Asia, the cannabis plant has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries. Tetrahydrocannabinol (THC) is the main psychoactive component of cannabis, which is one of the 483 known compounds in the plant, including at least 65 other cannabinoids, such as cannabidiol (CBD). Cannabis can be used by smoking, vaporizing, within food, or as an extract.
- When will the Next T CrB Eruption Occur? (iopscience.iop.org)
The first eruption of the periodic nova T CrB for eighty years is anticipated soon, though with an unknown date. A refinement of the future eruption date is investigated. The investigation is based on the combination of the previous eruption dates and on the orbital ephemeris of the binary system, without any hypothesis on the eruption mechanism. It is predicted that the next eruption should appear around 2025 March 27 or November 10, or later.
