GRB 221009A was an extraordinarily bright and very energetic gamma-ray burst (GRB) jointly discovered by the Neil Gehrels Swift Observatory and the Fermi Gamma-ray Space Telescope on October 9, 2022.
Titanite crystal model. Titanite, or sphene (from Ancient Greek σφηνώ (sphēnṓ) ' wedge '), [5] is a calcium titanium nesosilicate mineral, Ca Ti Si O 5.Trace impurities of iron and aluminium are typically present.
The mineral is also referred to as lavulite, luvulite, and royal azel by gem and mineral collectors. [3] In Japan, sugilite is found as yellowish-white to colourless, and is not good for jewellery. [6] Sugilite on Matrix, Wessels Mine in Northern Cape Province, South Africa, size: 2.4 × 2.1 × 1.2 cm Sugilite owl and mouse, height 9 cm (3.5 in)
It is an aluminized (powdered aluminum) explosive having the same order of sensitivity as Composition B. [1]Tests indicate that it is about 98% to 100% as powerful as Torpex, that it is definitely less sensitive than Torpex in both laboratory impact and bullet impact, that it is slightly more sensitive in these respects than TNT, and that it is about the same order as Composition B. [2]
The burst lasted for 23 minutes, almost 700 times as long as the two-second average for high energy GRBs. [2] Follow-up observations were made 32 hours after the blast using the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) on the 2.2 metre telescope at the European Southern Observatory in La Silla , Chile , allowing astronomers to ...
RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive and a key ingredient in Semtex. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, [2] with a relative effectiveness factor of 1.60.
Either a long-duration burst in which the presence of a bright supernova is ruled out, or a short-duration burst with extremely long-lasting gamma-ray emission. GRB 080319B: z = 0.937: Swift: The most (optically) luminous event of any nature observed in the universe to date. By far the brightest optical afterglow of any gamma-ray burst. GRB 080916C
A ZSU-23-4 targeted by munitions missile AGM-154 Joint Standoff Weapon during an exercise.. The BLU-97/B Combined Effects Bomb is the submunition used in several cluster bomb type weapon systems, mainly the CBU-87 and its precision-guided version CBU-103.
