The left panel shows a NIRCam in-focus image at 2.12 microns, while the middle and right panels display defocused NIRCam images at two different positions, used to assess the telescope’s alignment. NASA’s James Webb Space Telescope (JWST) is the largest and most powerful space telescope ever launched, featuring a mirror made up of 18 […]

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 […]
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.

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 […]
NOAA Releases First Images from the World’s First Operational Space-Based Coronagraph.
NOAA has released the inaugural images from the Compact Coronagraph (CCOR-1), the world’s first operational, space-based coronagraph, aboard the newly launched GOES-19 satellite. CCOR-1 began its observations of the sun’s corona—the faint outermost layer of the solar atmosphere—on September 19, 2024. The primary function of CCOR-1 is to monitor the corona to predict coronal […]
The Unfathomable Depths: Exploring the Mystery of Black Holes.
The universe is filled with enigmatic objects that challenge our understanding of physics, and black holes are among the most mysterious. The term “black hole” was popularized by physicist John Wheeler in 1967 during a lecture on gravitational collapse. It perfectly captures the essence of these dark regions that swallow light and matter, rendering […]
Supernovae: Cosmic Explosions and Their Legacy.
When massive stars reach the end of their brief lives, they explode in dazzling displays known as supernovae. These events are some of the most energetic phenomena in the universe, emitting intense bursts of light and material that can outshine entire galaxies for a short period. One prominent example is the spiral galaxy NGC […]
ESA Advances Space Sustainability with RISE In-Orbit Servicing Mission.
The European Space Agency (ESA) is making significant strides toward sustainability in space with its inaugural in-orbit servicing mission, RISE. A €119 million contract has been awarded to D-Orbit, which will act as the prime contractor for this commercial mission. Mission Overview. RISE aims to demonstrate the capability to rendezvous with and dock to […]
