There’s something magnetic about Sagittarius. This zodiac sign, active from November 22 to December 21, carries a spark that feels instantly recognizable—bold, curious, and constantly on the move. Sagittarius blends passion, intensity, and flexibility in a way that sets them apart. Their symbol, the archer, reflects a spirit that shoots toward distant horizons, eager to uncover meaning in places many people would skip. From remote rivers to historic sites filled with forgotten stories, Sagittarius pursues knowledge with an energy that rarely slows down. The Core Nature of Sagittarius Sagittarius is the final fire sign, and its traits burn with motion and curiosity. This sign is mutable, which explains its constant pull toward change and exploration.

In his newest deep-space image, astrophotographer Greg Meyer turns the cosmos into a canvas. His subject — a nebula shaped like a furious baboon — has been dubbed the Rampaging Baboon Nebula. Streams of gas and dust weave through the frame, glowing in hues that give the scene a startling sense of movement. The photograph spotlights the complex beauty and creative chaos that define our galaxy’s stellar nurseries. A Nebula Like No Other The nebula lies about 500 light-years away in the constellation Corona Australis. Its shape suggests the face of a mandrill, with molecular dust sculpting the mouth and facial contours. The bright blue eyes are created by reflection nebulas that scatter starlight, adding a...
Mars has always been a planet of mystery, but fresh research suggests the Red Planet hides something far more unusual beneath its surface. Instead of a neatly layered interior, scientists have discovered that Mars’ mantle may be filled with giant chunks of rock left over from its violent early years. This finding reshapes the way experts view the inner structure of the planet and offers a rare glimpse into conditions dating back more than 4 billion years. Mars’ Messy Interior When most people think about the inside of a planet, the picture is often a series of tidy layers stacked one on top of another, like a clean geological cake. Mars, however, refuses to fit that...
Lightning might seem like a sudden burst from the sky, but the science behind it runs deep—and recent research has added an electrifying twist. Scientists have long known that thunderstorms build electrical charges until they discharge in brilliant flashes of lightning. What’s new is the evidence pointing to an unexpected trigger: cosmic rays. Researchers at Los Alamos National Laboratory have uncovered clues that suggest lightning may actually start with particles from outer space, opening a fresh angle on this natural phenomenon. A Shift in Understanding Thunderclouds have always been the stage for lightning. Traditional understanding says it begins when opposite charges build up in a storm—positive at the top, negative at the bottom. Once the difference...
The Vera C. Rubin Observatory has officially raised the bar for what “big data” means in astronomy. After releasing its first batch of cosmic images, the observatory isn't just capturing the night sky—it's creating one of the most extensive visual datasets humanity has ever seen. Powered by the world’s largest digital camera, the images are so detailed and expansive that processing them requires not just high-speed networks, but a whole digital ecosystem: seven international data brokers, three massive data centers, and a uniquely named management system called the Data Butler. The Scale of Rubin’s Cosmic Images What makes Rubin Observatory's contribution truly staggering is the sheer volume and precision of the data it collects. Once it...
In a groundbreaking observation, astronomers have captured an extraordinary moment in the cosmos—a high-speed, high-stakes confrontation between two galaxies over 11 billion light-years away. This isn’t just any merger. It’s a rare, aggressive event where one galaxy is striking the other with intense quasar radiation, dramatically changing its ability to form new stars. This unprecedented sighting is now offering a deeper look into how galaxies interact, evolve, and sometimes collide with devastating consequences. The "Cosmic Joust"—When Galaxies Collide Researchers used the combined power of ALMA and the Very Large Telescope (VLT) in Chile to observe two galaxies locked in what they describe as a “cosmic joust.” The term goes beyond metaphor—it reflects the actual movement. These...
NASA’s James Webb Has Pulled Back The Curtain To Understanding The Universe’s Earliest Galaxies Better
Just a few days into its scientific operations, NASA’s James Webb Space Observatory has already piqued scientists’ interest. They did that in a region of early galaxies. Those that had been beyond the reach of any other telescope.
Galaxies / NASA’s new discovery leads us to a novel perspective of the cosmos, argue scientists.
The things we perceive are entirely novel. “Webb is telling us that there’s a rich cosmos beyond what we thought,” said Tommaso Treu, principal investigator on one of the Webb initiatives from the University of California, Los Angeles. Yet again, the cosmos has taken us by surprise. In many respects, these early galaxies are exceptional.
What Is Taking Place?
There are now two studies in the Astrophysical Journal Letters, led by researchers Marco Castellano of the National Institute for Astrophysics in Rome, Italy. And Rohan Naidu of the Harvard-Smithsonian Center for Astrophysics and the Massachusetts Institute of Technology in Cambridge, Massachusetts.
Reuters / NASA discovers two “novel” galaxies that existed after 400 million years of the Bing Bang.
These first results come from two Early Release Science (ERS) programs on board the Webb spacecraft: the Grism Lens-Amplified Survey from Space (GLASS) and the Cosmic Evolution Early Release Science Survey (CEERS).
However, scientists analyzed the GLASS-JWST data over four days and discovered two brilliant galaxies. Though future spectroscopic studies with Webb will help confirm, these galaxies likely existed about 450 and 350 million years after the big bang (with a redshift of around 10.5 and 12.5, respectively).
What Has It Previously Been?
Additionally, a more distant GLASS galaxy, designated GLASS-z12, whose age is estimated to be 350 million years after the big bang, was discovered using Webb. “With Webb, we were shocked to see the most distant starlight anybody had ever seen,” stated Naidu.

Astronomy has now entered a brand-new era and with cutting edge scientific equipment, it’s like discovering an unknown city or artifact during an archaeological investigation. Scientists believe these technological advancements will facilitate the discovery of even more early galaxies by Webb in future deep sky surveys.
Moreover, these galaxies began to clump together. “Also, no one predicted that the Middle Ages would finish so quickly,” said Garth Illingworth of the University of California, Santa Cruz. Additionally, he has worked on the Naidu/Oesch project. The age of the cosmos back then would have been just a tenth of what it is now. In the grand scheme of the 13.8 billion-year-old expanding universe, it’s a blink of an eye.
What Followed After?
Illingworth noted the brightness of the two galaxies discovered by these groups. There are no ultra-bright, ancient stars in our immediate vicinity. Moreover, to be sure, the most distant source is relatively compact. Its colors suggest that its stellar population is mainly free of heavy elements. It maybe even contains some Population III stars. Adriano Fontana, a member of the GLASS-JWST team and the second author of the Castellano et al. research, emphasized that only Webb spectra would provide definitive evidence.
Similarly, infrared color measurements determine the Webb distance to these two galaxies. No other observatory compares to the James Webb Space Telescope regarding space research. Webb will investigate the origins and structure of the cosmos and the existence of additional planets outside our solar system.
