NASA's diminutive BurstCube satellite is now making its way to the International Space Station (ISS) aboard SpaceX's Dragon resupply spacecraft. It lifted off at 4:55 p.m. EDT on Thursday, March 21, from Launch Complex 40 at Cape Canaveral Space Force Station in Florida, BurstCube is poised to embark on a significant mission.BurstCube Satellite Mission ObjectiveUpon arrival at the ISS, BurstCube will be unpacked and subsequently released into orbit. Its primary objective? To detect, locate, and analyze short gamma-ray…

The Indian Space Research Organisation (ISRO) again made a big discovery courtesy Astrosat space telescope by capturing a massive gamma-ray explosion. These gamma-ray bursts are considered as being the most powerful explosions known in the universe. Astrosat space telescope is India's first multi-wavelength space telescope. The burst that was captured is the telescope's 600th detection of such a massive GRB explosion. Experts believe that gaining further knowledge of the phenomenon can provide more understanding of…

The gamma-ray burst, affectionately dubbed ‘BOAT’ (Brightest of All Time), has been found to emit gamma-rays with energies reaching up to 13 teraelectronvolts, as revealed by a collaboration of scientists who have studied these emissions.Dominic Monaghan on Attending Fan ConventionsGamma-ray bursts are the brightest explosions the cosmos has to offer, besides the Big Bang—the explosion that happened 13.77 billion years ago that marks the beginning of time. The BOAT was detected on the morning of October 9, 2022, by the…

Gamma-ray bursts are extremely energetic explosions caused by some of the cosmos’ most remarkable objects: black holes, neutron stars, and the violent deaths of stars. Now, astronomers have found evidence of gamma-ray bursts emerging from the collisions of stars.Stay in Your Seats, It's Gonna Be a Bumpy Flight | Extreme EarthThe evidence was found using observations made by the Gemini South telescope in Chile (which is operated by the National Science Foundation’s NOIRLab), the Nordic OpticalTelescope, and the Hubble…

Surprisingly, NASA’s Astronomy Picture of the Day is not a spectacular view of the cosmos, but a periodic table! Read on to know why. Each day, NASA features a different image of our fascinating universe along with a brief explanation written by a professional astronomer. Today, the image neither features any breathtaking image of a galaxy in the deep cosmos nor reveals an unseen image of our biggest star, our Sun. Instead, NASA dedicated today's astronomy picture of the day to the periodic table of elements. If you…

A recent NASA study could change the understanding of gamma-ray bursts and black hole formation. Know all about it here. Almost a year ago on December 11, Earth was witness to a high energy gamma-ray burst (GRB) which was suspected to be emitted from the outskirts of a galaxy around 1 billion light-years away. What made this cosmic burst unusual was the fact that it did not submit to any one pre-defined category of gamma-ray bursts. It left scientists baffled and put a doubt into their previous understanding of…

They alerted other scientists to the event, and several telescopes quickly pivoted to focus on the flash. Now, two teams of researchers have identified its source: a black hole feasting in the distant universe.Black holes are famously dark; their gravitational pull is so…

Astrophysicists have developed the first 3D simulation of the entire evolution of a jet from its birth by a rotating black hole to its emission far from the collapsing star.Simulation shows that as the star collapses, its material falls on the disk that swirls around the black hole. This falling material tilts the disk, and, in turn, tilts the jet, which wobbles as it struggles to return to its original trajectory.The wobbling jet explains the longstanding mystery of why Gamma-ray Bursts blink and shows that these bursts…
