The power of Indian astrophysics has once again been showcased with the detection of a powerful gamma-ray flare from a distant galaxy that dates back to a time before the formation of Earth. This remarkable discovery was made using India’s Major Atmospheric Cherenkov Experiment (MACE) telescope, which was inaugurated in Hanle, Ladakh, on October 4, 2023. The MACE telescope, situated at an altitude of approximately 4.3 km above sea level, observed this high-energy burst from a source located 8 billion light-years away. This means the flare originated long before Earth came into existence, providing a unique glimpse into the early universe.
Gamma-ray bursts are the most intense explosions in the universe, typically occurring when massive stars collapse or when black holes merge. For context, scientists estimate that Earth was formed around 4.5 billion years ago, making this flare significantly older than our planet. This discovery underscores the ongoing quest to understand the origins and evolution of the universe, a quest that has captivated scientists and stargazers alike for decades.
On January 26, 2025, Mumbai’s Bhabha Atomic Research Centre (BARC) also spotted a powerful burst of gamma rays from a quasar called OP 313 (also known as B2 1308+326). According to scientists, this burst is located 8 billion light-years away, “which is said to have happened about 3.5 billion years before Earth even existed”
.
A light-year is a unit of distance that measures how far light travels in one year, with light moving at a speed of around 186,000 miles per second, which means it takes about eight minutes to reach Earth from the Sun.
It implies that when we see the Sun, we are seeing it eight minutes later rather than as it is at the moment. The distance between the Sun and Earth is approximately 93 million miles.
Unlike any other telescope, MACE is designed for high-energy astronomy and focuses on cosmic events such as supernovae, black holes, and dark matter.
The Major Atmospheric Cherenkov Experiment Telescope, or MACE, was built with 356 mirror panels, a diameter of 21 meters, and a weight of 180 tons. It is the highest telescope in the world and the largest in Asia
It is equipped with a 1,200-kilogram high-resolution imaging camera, designed to capture the finest details of the cosmos.
The implications of this research are profound. The gamma-ray flare observed by MACE offers scientists a unique window into the early universe, providing insights into the conditions and events that shaped the cosmos billions of years ago. This discovery also highlights the advancements in astrophysical research, particularly in the field of gamma-ray astronomy.
For the general American public, this discovery brings to mind the mystique and wonder of space exploration. It reminds us of iconic artists such as Astronaut Neil Armstrong, and scientists from Johnson Space Center.
The practical applications of such research could lead to advancements in fields such as particle physics, cosmology, and astrophysics. The research could pave the way for new technologies and understanding of the fundamental laws of the universe.
