On August 7, 2023, the Sun emitted a powerful solar flare, peaking at 4:46 p.m. EDT. NASA’s Solar Dynamics Observatory (SDO) captured an image of the event, which showed a subset of extreme ultraviolet light that revealed extremely hot material colorized in yellow and orange. This solar flare was classified as an X1.5 flare, meaning […]

What mystery of the space movie Crab Pulsar does it reveal?
The Crab Nebula is an awe-inspiring celestial spectacle, and now, combination of new observations from NASA’s Chandra X-ray Observatory and Hubble Space Telescope, we can see its inner workings. Just when it seemed like the summer movie season had ended, two of NASA’s Great Observatories have produced their own action movie featuring the Crab pulsar […]
Hubble glimpses a galaxy cluster twinkling and shining like a diamond.
Seen a cluster of stars twinkling and glittering like diamonds in the night? What you may not know is that those stars are actually part of a larger globular cluster, a celestial phenomenon that scientists are only just beginning to understand. One of the most impressive globular clusters out there is NGC 6652, a star-studded […]
Astronomers have discovered an unexpectedly quiet and distant galaxy cluster.
The discovery of the most distant galaxy cluster, SPT-CL J2215-3537 (SPT2215 for short), is providing astronomers with some much-needed insight into how these gigantic structures formed and why the universe looks like it does today. This is due to the fact that this cluster is located 8.4 billion light-years away and is unusually young, meaning […]
Do spiral stars provide an opportunity to learn about the early universe?
Astronomers have been captivated by a mysterious phenomenon occurring in the Small Magellanic Cloud, a satellite galaxy of the Milky Way. Young stars have been observed spiralling into the centre of a massive cluster of stars, an oddly shaped stellar nursery known as NGC 346. A river-like motion of gas and stars appears to […]
How was the journey of 11 years of Messenger spacecraft?
When we look up at the night sky, we can’t help but be in awe of all of the planets we can see with the naked eye. Mercury has always been a bit of an enigma, however, due to its proximity to the Sun and its relative lack of visibility. For centuries, scientists have been […]
Is Archean phosphorus recycling possible by ultraviolet radiation?
The Proceedings of the National Academy of Science recently published the study “Archean phosphorus recycling facilitated by ultraviolet radiation.” This study examines how ultraviolet radiation from the early Earth could have helped recycle phosphorus and may have played an important role in the development of life during the Archean period. The importance of phosphorus […]
What do infrared images of the ‘El Gordo’ galaxy cluster, taken by Webb, reveal?
Have you ever heard of El Gordo? No, we’re not talking about a person – rather, El Gordo is a galaxy cluster.Recently, the NASA/ESA/CSA James Webb Space Telescope has captured an infrared image of El Gordo that reveals a bounty of never-before-seen objects. El Gordo, meaning the “Fat One” in Spanish, is located 6.2 billion […]
Northrop Grumman’s 19th Cargo Flight to the Space Station.
The Northrop Grumman Cygnus resupply spacecraft is on its way to the International Space Station (ISS) with over 8,200 pounds of NASA science investigations and cargo, after launching at 8:31 p.m. EDT Tuesday from the agency’s Wallops Flight Facility in Virginia. This mission marks the ninth commercial flight for Northrop Grumman in support of […]
In 2013, Hubble determined the true visible-light color of a giant planet.
Astronomers made discovery about a planet located 63 light-years away. The planet, named HD 189733b, is the closest exoplanet to Earth that can be seen crossing the face of its star. Using the powerful Hubble Space Telescope, astronomers deduced the visible-light color of the distant world. At a glance, the planet appears to be […]
