The Milky Way's supermassive black hole is leaking gas

The supermassive black hole at the center of our Milky Way galaxy is leaking.

The Milky Way's central black hole, known as Sagittarius A* (Sgr A*), has been "leaking" or emitting jet-like superheated beams for several thousand years. In a composite image captured with the Hubble Space Telescope, researchers have revealed bright X-ray radiation as well as bright clouds of molecular gas and heated ionized gas near the black hole.

Our galaxy's central monster black hole hasn't been directly photographed, nor has its "leaky" jet. But by using observations like the new image, scientists can see the effects of the black hole's "blowtorch-like jet" effects, providing evidence for its existence and how it behaves.

The composite image shows hydrogen gas as orange-colored features. In interpreting the composite image, the top of this cloud of orange gas, the black hole's jet is seen colliding with the hydrogen gas before scattering upwards into "tendrils," NASA said in a statement. You can also see superheated gas in blue and molecular gas in green, as captured in X-ray observations.

Russia aims to rekindle moon program with lunar lander launch this July

Russia is ready to reactivate its moon exploration agenda, a former Soviet Union enterprise that ended decades ago. The last in the series of pioneering Soviet robotic lunar missions was Luna 24, which sent about 6 ounces (170 grams) of moon material back to Earth in 1976. Russia's planned Luna 25 mission is set to kick-start a sequence of lunar outings that also involves Europe and China . For example, Russia intends to collaborate with China on the International Lunar Research Station, which is targeted to be operational by 2035. Russia's rekindling of its lunar exploration objectives would clearly be bolstered by the success of Luna 25 , a lander mission scheduled to launch But how Russia and China's moon exploration plans will truly jell, and how this partnership might influence NASA's lunar "rebooting" via its Artemis program, are not clear.this July. Main Tasks Luna 25 is designed to operate on the surface of the moon for at least one year, ma...

Agnikul opens India's first rocket engine factory in Chennai

Space tech startup Agnikul Cosmos today inaugurated India's first-ever facility to manufacture 3D-printed rocket engines in Chennai. Named Rocket Factory 1, it was unveiled by Tata Sons chairman N Chandrasekaran and Isro chairman S Somanath in the presence of Pawan Goenka, the chairman of IN-SPACe (Indian National Space Promotion and Authorization Centre). The 10,000-square-foot facility is located at IIT-Madras Research Park. It will have a 400mm x 400mm x 400mm metal 3D-printer from EOS that will enable end-to-end manufacturing of a rocket engine under one roof. The manufacturing facility has a capacity to make two rocket engines per week and thereby one launch vehicle every month, Agnikul co-founder Srinath Ravichandran told TOI. "This s a milestone for us as we go from R&D phase into core manufacturing with the opening of this facility, and begin productionizing the launch vehicle engine making. We have a lot of inbound interest [for launches] from global quarters...

NASA wants another moon lander for Artemis astronauts

Multiple private spacecraft will be ferrying NASA astronauts to the surface of the moon just a few years from now, if all goes according to plan. In April 2021, NASA picked SpaceX to build the first crewed lunar lander for the agency's Artemis program, which is working to put astronauts on the moon in the mid-2020s and establish a sustainable human presence on and around Earth's nearest neighbor by the end of the decade. But SpaceX apparently won't have the moon-landing market cornered: NASA announced today (March 23) that it plans to support the development of a second privately built crewed lunar lander. "This strategy expedites progress toward a long-term, sustaining lander capability as early as the 2026 or 2027 timeframe," Lisa Watson-Morgan, program manager for the Human Landing System Program at NASA's Marshall Space Flight Center in Alabama, said in a statement today. "We expect to have two companies safely carry astronauts in thei...
