First commissioned in 1957, parts of the telescope came from the World War 1 decommissioned battleships HMS Revenge and HMS Royal Sovereign. In 2019, the telescope was awarded UNESCO World Heritage Site status.
The BBC noted that the Jodrell Bank Lovell Radio Telescope was the only facility in the Western World able to track Sputnik in 1957. Among many other accomplishments, it was also instrumental in confirming the existence of pulsars as well as proving Einstein’s theory of relativity.

This week’s images of 16 galaxies are from a variety of NASA telescopes. The galaxies are generally sorted into three types – spiral, elliptical, and irregular. For example, the Milky Way galaxy is a spiral galaxy, whereas Centaurus A (Cen A above) is a giant elliptical galaxy and NGC 1569 (also above) is a compact dwarf irregular galaxy.

This week’s image is from the U.S. National Science Foundation’s (NSF) National Solar Observatory (NSO). It shows the highest resolution image ever captured of the Sun’s surface. The image was captured by the Inouye Solar Telescope located in Maui, Hawaii.
Using the world’s most powerful solar telescope, the NSF Daniel K. Inouye Solar Telescope near the summit of Maui’s Haleakalā, combined with computer simulations, an international team of scientists from the NSO, NSF NCAR High Altitude Observatory (HAO), and the Max Planck Institute for Solar System Research (MPS) found the signature of Kelvin-Helmholtz instability (KHI), tiny swirling patterns like small whirlpools, on the Sun’s surface. Researchers suggest that KHI might be a key reason why the Sun’s outer atmosphere gets so hot, and why magnetic energy builds up and moves around on the Sun. Magnetic energy fuels solar flares and eruptions—the kind of solar activity that can send bursts of energy toward Earth and affect satellites, power grids, and other technology. The discovery opens a new window into the fundamental physics of the Sun and other stars while underscoring the unmatched capabilities of the Inouye Solar Telescope.
“It is exciting to see ideas from AI and reinforcement learning brought to telescope scheduling, where every decision must balance changing conditions and scarce observing time…Developing intelligent scheduling systems for astronomical surveys also raises fascinating new machine learning problems, and we are excited to continue exploring them through this project.”
-Statement by Northwestern University’s Aravindan Vijayaraghavan, who co-led the AI telescope project with Drlica-Wagner, as quoted by NOIRLab. The AI program planned and managed observations on a national facility for the first time. It is hoped that the involvement of AI could add efficiencies to the process, thereby allowing astronomers to have more time for their science.
Jodrell Bank Observatory, the hub of a world-leading network of radio telescopes, is facing closure after government funding for the facility was slashed. Scientists say decision is blow to UK astronomy as deep space observatory is home to world-leading facilities. The deep space observatory includes the Grade I-listed Lovell telescope and is prized by astronomers who study galaxies, black holes, star formation, planets beyond the solar system and the afterglow of the big bang.
A telescope can spend hours collecting the faint light of a distant galaxy. A fast-moving satellite needs only a few seconds to cross its field of view, leaving a bright streak that contaminates (and sometimes ruins) the long exposure.As the number of satellites around Earth grows, astronomers increasingly need ways to predict and avoid these crossings. Researchers at the University of Warwick are now developing an early-warning system that could spot an approaching satellite and alert a telescope before it enters the image.
Europa, one of Jupiter’s icy moons, long has fascinated scientists because of what may lie beneath its frozen shell: a global ocean of liquid water.That hidden ocean has made Europa one of the most compelling places in the solar system to study the conditions that might support life. But new research led by Rutgers scientist Lujendra Ojha suggests one of the most promising shortcuts to Europa’s ocean may be far more complicated than previously thought.
