DART Mission: Success in Changing the Asteroid’s Orbit

NASA’s Double Asteroid Redirection Test (DART), the world’s first planetary defense technology, successfully impacted the orbit of the asteroid Dimorphos. After a 10-month journey, DART targeted Dimorphos and altered the asteroid’s orbit. This mission was conducted as part of Earth’s protection strategy against potential threats. The change in the asteroid’s orbit demonstrated that a connected asteroid to Earth could be moved. The success of DART is considered a significant step in planetary defense.

OJ287: Mysteries of the Massive Supermassive Black Hole Pair

OJ287, a quasar located 5 billion light-years away from Earth, hosts an enormous supermassive black hole with a mass of 18 billion solar masses at the center of an active galaxy. Alongside this black hole, there is a second black hole with a mass of 150 million solar masses that orbits in a tilted plane and had previously been spinning. The smaller black hole collides with the feeding disk of the larger black hole every 12 years, producing flashes brighter than trillions of stars. Recent studies have revealed separate emissions from the feeding disks of both supermassive black holes. This discovery indicates that OJ287 is the best candidate for supermassive black hole pairs and is regularly monitored by observatories worldwide.

The Mystery of Gamma-Ray Burst: Getting Closer to the Source of GRB 191019A

Astronomers focusing on the source of an event called GRB 191019A discovered a long-duration gamma-ray burst (GRB). This GRB was promptly detected by the Neil Gehrels Swift Observatory. Astronomers spent months examining the faint final light of the source, revealing a stellar death scene at the dense center of a galaxy located 3 billion light-years away. The source of the GRB flash was found just 100 light-years away from the supermassive black hole at the center of the galaxy. This discovery was regarded as an exciting development in understanding stellar deaths and unexpected sources of gravitational waves.

The Clouds of Venus Could Support Life

A study published in Astrobiology examines the possibility of life existing within the thick cloud layers of Venus. Researchers evaluate various factors such as energy requirements, chemical energy, hydrogen and metal scarcity, cloud acidity, water activity, and the mass of the Venus cloud biosphere to assess the likelihood of life in the clouds of Venus. However, further research is needed to provide conclusive evidence of life on Venus.


Internet Connection on Mars

The article titled “Expanding Earth’s Internet to Mars with Space Data Servers” addresses the necessity of a robust communication infrastructure for humans living on Mars and space missions. It suggests that the use of data servers in space would facilitate communication between Earth and Mars and provide access to the internet on Mars colonies. However, the establishment of such infrastructure involves technical and financial challenges.
