A nearby world strengthens the search for habitability Astronomers have identified a promising super-Earth, GJ 3378b, located just 25 light-years from Earth, placing it among the closest potentially habitable exoplanets discovered to date. Its proximity offers rare opportunities for future atmospheric study, making it a key target in the ongoing search for environments

Cosmic Origins Written in Ice Scientists have identified direct physical traces of stardust preserved in Antarctic ice, offering rare confirmation that material forged in supernova explosions has reached Earth in measurable quantities. The discovery provides new insight into how elements created in distant stellar deaths are distributed across interstellar space and eventually incorporated into planetary environments. Supernova Dust and th

A Planet That Should Not Exist in This Orbit Astronomers have long believed that planets orbiting close to a star cannot survive its transformation into a red giant and eventual collapse into a white dwarf. However, the discovery of WD 1856b has challenged that assumption. The Jupiter-sized planet orbits its dead star at an extremely close distance, completing a full orbit in just over a day, defying traditional models of stellar evolution and planetary survival.

Interstellar comet 3I/ATLAS reveals origins in an alien solar system as astronomers analyzing the rare celestial object have uncovered evidence suggesting it formed in conditions vastly different from those that shaped our own planetary system. The comet, known as 3I/ATLAS, was first detected passing through our solar system in July and is only the third known interstellar object ever observed in such a trajectory. New findings, published on Wednesday, April 23, 2026, in the journal Nature Astronomy, indicate that the comet likely originated in an extremely cold and distant region of another planetary system. Researchers used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to observe the comet in early November, shortly after it made its closest approach to the sun. The study marks the first time scientists have detected deuterium, a heavier isotope of hydrogen, in an interstellar object. This form of hydrogen is typically found in deuterated water, also known as semi-heavy water. According to lead researcher Luis Eduardo Salazar Manzano of the University of Michigan, the concentration of deuterium in 3I/ATLAS is more than 40 times higher than levels found in Earth’s oceans and over 30 times higher than in comets within our solar system. Such unusually high levels suggest that the comet formed in an environment with extremely low temperatures—below 30 Kelvin, or approximately minus 405 degrees Fahrenheit. Scientists believe this indicates formation in the outer regions of a protoplanetary disk, far from its host star, where icy materials can preserve their original chemical signatures for billions of years. Further analysis suggests that 3I/ATLAS may be up to 11 billion years old, making it significantly older than our solar system, which formed about 4.5 billion years ago. The preserved water within the comet likely dates back to the early stages of the Milky Way, offering a rare glimpse into the galaxy’s ancient conditions. Researchers also noted that standard water (H₂O) was not directly detected during observations, likely due to instrument sensitivity limits. However, the clear detection of deuterated water underscores the comet’s unusual composition and reinforces its value as a scientific “time capsule.” Experts say interstellar objects like 3I/ATLAS provide unique insights into how planetary systems form and evolve across the universe. Future observations from facilities such as the Vera C. Rubin Observatory are expected to identify more such objects, potentially helping scientists determine whether 3I/ATLAS is an anomaly or part of a broader population of chemically distinct comets. By studying these rare visitors, astronomers hope to better understand how the composition of planets—and even the building blocks of life—may differ across the galaxy, offering new perspectives on the origins of planetary systems beyond our own.

The 2026 Solar Eclipse will occur on February 17, and it is set to be a remarkable celestial event. This eclipse will be an annular solar eclipse, often referred to as the Ring of Fire eclipse. Here's everything you need to know about this rare event: Eclipse Type: The eclipse will be an annular solar eclipse. In this type of eclipse, the Moon will cover about 96% of the Sun, but due to the Moon being farther from Earth, it will appear slightly smaller than the Sun. As a

The night sky turned into a spectacular display on Wednesday as the November 2025 supermoon — also known as the Beaver Moon — rose in its full brilliance, becoming the largest and brightest full moon of the year. This remarkable celestial event, visible across much of the world, drew stargazers and sky enthusiasts to open fields, terraces, and observatories to witness its glowing beauty. The November supermoon is the second in a sequence of three supermoons occurring in 2025, an

NASA’s discovery of interstellar comet 3I/ATLAS has sparked global interest after Harvard astrophysicist Avi Loeb suggested it could be a form of alien technology. Detected on July 1, 2025, the comet is only the third known interstellar object to pass through our solar system. While NASA confirmed that 3I/ATLAS poses no threat to Earth, Loeb and other researchers argue that its unique chemical and physical properties set it apart from natural space objects, warranting a deeper investigation

Asteroid 2025 QY4 is drawing the attention of both scientists and astronomy enthusiasts as it prepares to make a close approach to Earth this week. The asteroid, which belongs to the Aten group of space rocks known for orbiting across Earth’s path, measures nearly 180 feet in diameter and is travelling at an astonishing speed of more than 39,000 miles per hour. Its size and velocity make it an object worth monitoring, even though experts have already conf
