An international team of researchers has observed part of the formation of a dwarf galaxy, helping to explain how they evolve from a dwarf state to maturity. In their paper published in the journal Nature, the group describes finding evidence of maturation in such galaxies.

Prior research has shown that there are dwarf galaxies in the universe. Such galaxies are typically made up of just a few billion stars, as compared to mature galaxies such as the Milky Way, which have 200 to 400 billion stars. Prior research has also suggested that some dwarf galaxies might evolve to become more mature galaxies, but how that might happen has not been clear. In this new effort, the researchers focused the AstroSat space-based telescope on several blue compact dwarf galaxies, which are calculated to be approximately 1.5 to 3.9 billion light-years from Earth. The team then used the ultraviolet imaging telescope aboard AstroSat, which is India’s first multi-wavelength space telescope, to look for evidence of star formation activity.

Prior efforts to observe star formation in dwarf galaxies have been hindered by their low luminosities, small size and the low mass of the objects they contain. These problems have been overcome with AstroSat due to the high resolving power of its telescope and because of its ability to capture multiple wavelengths of light at the same time, and also because it was fitted with UV deep field imaging technology.

A new type of technology has recently been developed. AI technology that mimics the human eye. Researchers at the University of Central Florida have created a device for AI that replicates the retina of the eye. This new discovery can lead to AI that can immediately identify objects, such as automated descriptions of photos captured with a camera or a phone. This technology can potentially be used in autonomous robots and self-driving cars as well.

Researchers have been trying to build artificial synapses for years in the hope of getting close to the unrivaled computational performance of the human brain. A new approach has now managed to design ones that are 1,000 times smaller and 10,000 times faster than their biological counterparts.

Despite the runaway success of deep learning over the past decade, this brain-inspired approach to AI faces the challenge that it is running on hardware that bears little resemblance to real brains. This is a big part of the reason why a human brain weighing just three pounds can pick up new tasks in seconds using the same amount of power as a light bulb, while training the largest neural networks takes weeks, megawatt hours of electricity, and racks of specialized processors.

That’s prompting growing interest in efforts to redesign the underlying hardware AI runs on. The idea is that by building computer chips whose components act more like natural neurons and synapses, we might be able to approach the extreme space and energy efficiency of the human brain. The hope is that these so-called “neuromorphic” processors could be much better suited to running AI than today’s computer chips.

‘May the forest be with you.’The GEDI system aboard the ISS shoots laser beams down at Earth to fight deforestation.

The Food and Agricultural Organization (FAO) of the United Nations is building new digital tools to help fight deforestation and climate change. One of these is the FAO’s Framework for Ecosystem Monitoring (FERM) website, which uses satellite images to highlight the negative impact on forests worldwide.

The countdown now begins for China’s next uncontrolled rocket reentry in October.

China’s Long March 5B rocket crashed into the Indian Ocean in an uncontrolled reentry over the weekend. * NASA’s Bill Nelson criticized China’s space practices, citing a “risk of loss of life and property”. * China will launch another Long March 5B to orbit in October.

China’s Long March 5B rocket core stage reentered Earth’s atmosphere on Saturday, July 24.

The U.S. Space Command’s proposed move to Huntsville passed a big test July 13 when the Pentagon released a draft environmental assessment finding “no significant impacts on the human or natural environment” if the headquarters is built on the Redstone Arsenal site.

Although there remain four steps ahead of the move, Republican U.S. Sen. Tommy Tuberville of Alabama said the environmental assessment should be the last major hurdle for the plan to move the command from startup headquarters in Colorado to a permanent site. The move would bring 1,800 headquarters staff and their families to north Alabama.

“The Redstone Arsenal site is the (Department of the Air Force’s) Preferred Alternative for implementation of the Proposed Action,” the environmental assessment said. The proposed action is a permanent headquarters.

International scientists disocvered a tertiary, or triple, star system with a third star orbiting a binary of two stars. The stars are massive in size.

Spacecraft set to launch on 2 August will study surface weathering in a new way, measure magnetic fields, and peer into dark craters.
