Chandra X-ray Observatory Helps Astronomers Discover a Surprisingly Lonely Galaxy There is a surprisingly lonely galaxy about 9.2 billion light-years from Earth.
Yerkes Observatory in Williams Bay, the birthplace of modern astrophysics, announced on May 10 the appointment of Dr. Amy Steele as its new Director of Astronomy and Research.
Coming to Yerkes from the Trottier Space Institute in Montréal, Quebec, Canada, Steele studies the building blocks of planets living around stars like our sun that have reached the final phase of their lives. She will begin her role in June, reporting to Yerkes’ Montgomery Foundation Deputy Director and Head of Science and Education Dr. Amanda Bauer.
“The opportunity to lead the direction of astronomy and research at Yerkes is a dream come true for me as an astronomer,” Steele said. “It is an honor to be able to work alongside an adventurous and passionate team who share the same love for this observatory and communion with the night sky. I am truly excited to collaborate with my colleagues and the Yerkes Future Foundation to inspire astronomers young and old, near and far, to follow their curiosity and chase their dreams.”
Astronomers have created a stunning mosaic of baby star clusters hiding in our galactic backyard. The montage, published Thursday, reveals five vast stellar nurseries less than 1,500 light-years away. To come up with their atlas, scientists pieced together more than 1 million images taken over five years by the European Southern Observatory in Chile. The observatory’s infrared survey telescope was able to peer through clouds of dust and discern infant stars never seen before. Researchers say the observations will help them better understand how stars evolve from dust.
On April 28, NASA and its partners achieved another major milestone in the future of space communications — achieving 200 gigabit per second (Gbps) throughput on a space-to-ground optical link between a satellite in orbit and Earth, the highest data rate ever achieved by optical communications technology.
These data rates are made possible by using laser communications, which packs information into the oscillations of light waves in lasers, instead of using radio waves like most space communications systems.
-optical and even free space optics seems to be the future. People need to think about this when making devices.

The findings suggest the star Fomalhaut may have orbiting planets hidden among its rings of debris.
An international team of astronomers including several Dutch researchers has observed, for the first time, the benzene molecule (C6H6) in a planet-forming disk around a young star. Besides benzene, they saw many other, smaller carbon compounds and few oxygen-rich molecules. The observations suggest that, like our own Earth, the rocky planets forming in this disk contain relatively little carbon. The scientists published their findings in the journal Nature Astronomy.
The researchers studied the young, small star J160532 (one tenth of the mass of our sun) some 500 light years away from us towards the constellation Scorpio. Around such small young stars, many rocky planets similar to Earth form, in disks made of gas and dust. Until now, it has been difficult to study molecules in the warm inner part of these disks where the majority of planets form due to the limited sensitivity and spectral resolution of previous observatories.
For their research, the scientists used data from the MIRI spectrometer aboard the James Webb Space Telescope. MIRI can see right through dust clouds and is particularly well suited to measure hot gas in inner disks. The main optics of the MIRI spectrometer were designed and built by the Netherlands Research School for Astronomy (NOVA).
The company offers features such as a large window dome with a view of space, internet access via onboard Wi-Fi, and a dedicated room for exercise and rest at Haven-1.
We have entered a brand new era of space exploration, from flying a chopper on Mars to re-directing an asteroid’s trajectory to retrieving soil samples from a distant space rock.
The future of space is dynamic, with technological prowess allowing science fiction-inspired ideas to become reality. And next-generation space outposts are one such area that has piqued the interest of space startups. Especially since the International Space Station (ISS) is scheduled to be decommissioned by the end of this decade.
As well as helping us learn about the earliest galaxies in the universe and taking stunning images of parts of our solar system, the James Webb Space Telescope is also letting astronomers learn more about how planets form. Although we know that planets form from disks of dust and gas around stars called protoplanetary disks, there’s still a lot we don’t know about this process, particularly about how forming planets affect the rest of the system around them.
So it was an exciting moment when astronomers recently used Webb to study an asteroid belt in another planetary system and were able to peer into the rings of dust around the star to see where planets were forming.
Webb was used to study to study the Fomalhaut star, located in the constellation Piscis Austrinus, which is forming planets in a manner that is similar to what happened in our solar system around 4 billion years ago. The forming planets themselves aren’t visible, but the researchers could infer their presence based on the gaps in the dusty disk. They saw three concentric disks stretching a total of 14 billion miles from the star.
For the first time, astronomers have spotted an evolving star engulfing an orbiting planet.
When our Sun nears the end of its life, it will start to swell. During this expansion, which is expected to happen in some 6 billion years, the dying Sun will engulf our Solar System’s inner planets, including Earth. Though scientists are certain of Earth’s far-future fate, no direct observation had been made of a dying star swallowing an orbiting planet, until now [1].
The unique observation comes from Kishalay De of the Massachusetts Institute of Technology and his colleagues. The team found the planet-eating star in data taken as part of the Zwicky Transient Facility (ZTF), a large-area optical survey of the night sky. While comparing a few weeks’ worth of consecutive ZTF scans—a new survey of the sky is performed every 48 hours—a brightening star 12,000 light-years from Earth caught De’s attention, he says.
