NASA and ISRO’s NISAR Satellite to Revolutionize Disaster Monitoring and Earth Studies.
The NISAR mission will help researchers better understand Earth’s surface changes over time, including volcanic activity like the 2009 eruption at Mount Redoubt in Alaska. We often take for granted the dynamic and constantly shifting nature of Earth’s surface. From earthquakes to volcanoes, landslides to shifting glaciers, much of the planet is in perpetual […]
A Celestial Light Show: Hubble Reveals the Wonders of NGC 1672.
This captivating image from the NASA/ESA Hubble Space Telescope showcases the spiral galaxy NGC 1672, highlighted by the dramatic presence of a supernova. The Hubble Space Telescope has captured a stunning image of NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy, a cosmic symphony […]
Powerful Solar Flare Erupts, Reaching Earth on Nov. 6, 2024.
NASA’s Solar Dynamics Observatory captured this image of a solar flare on Nov. 6, 2024, with the bright flash in the center, showing extreme ultraviolet light that highlights the flare’s hot material in red. A massive solar flare erupted from the Sun at 8:40 a.m. ET on November 6, 2024, reaching a peak intensity […]
Astronomers Discover Rapidly Feeding Black Hole in Early Universe.
A groundbreaking discovery made by a team of astronomers using NASA’s James Webb Space Telescope (JWST) and Chandra X-ray Observatory has revealed a low-mass supermassive black hole at the center of a distant galaxy, only 1.5 billion years after the Big Bang. The black hole, located in the galaxy LID-568, is consuming matter at […]
NASA’s Parker Solar Probe Set for Historic Final Venus Flyby, Paving the Way for Closest Ever Solar Encounter.

Black Hole Insights: The Bekenstein-Hawking Formula and the Nature of Space-Time.
A groundbreaking formula established in the 1970s by Stephen Hawking and Jacob Bekenstein continues to illuminate our understanding of black holes and the fabric of space-time. Though first identified by Karl Schwarzschild in 1916, black holes remained largely theoretical for decades. “They were discovered as purely geometric objects—essentially, just empty space,” noted Yuk Ting […]
Exploring the Mystery of Vega: Insights from Hubble and Webb Observations.
Left: A false-color view from the Hubble Space Telescope reveals a 100-billion-mile-wide disk of dust around the star Vega. Hubble detects reflected light from smoke-sized particles forming a smooth halo on the disk’s periphery, with no large planets evident. The central black spot obscures the star’s bright glow. Right: The James Webb Space Telescope […]
30 years on, NASA’s wind technology is an unexpected achievement for studying our neighborhood in space.
In 1994, The first World Wide Web conference took place in Geneva, the Chunnel train traversed the English Channel, and the first Russian instrument on a U.S. spacecraft launched into deep space from Cape Canaveral. Among these mission was the launch of NASA’s Wind mission, designed to study the solar wind. It has since […]
Strong Solar Flare Erupts from the Sun on Hallowee.
NASA’s Solar Dynamics Observatory captured this image of a solar flare—visible as the bright flash in the upper left—on October 31, 2024, showcasing extremely hot material in extreme ultraviolet light, colorized in red. The Sun unleashed a powerful solar flare on October 31, 2024, peaking at 5:20 p.m. ET. NASA’s Solar Dynamics Observatory, which […]
