ISRO LVM3 Heavy-lift Rocket Launch: US BlueBird 6 Communications Satellite

ISRO LVM3 Heavy-lift Rocket Launch: US BlueBird 6 Communications Satellite








On Wednesday, Dec. 24, 2025, the Indian Space Research Organisation (ISRO) achieved another significant milestone for India's space program, successfully launching the LVM3-M6 rocket carrying the next-generation US communication satellite, BlueBird Block-2, from the Satish Dhawan Space Centre in Sriharikota. This mission highlights India's strengths in space technology and the critical role of ISRO’s heavy-lift vehicle, the LVM3 rocket, in the global space industry.

The LVM3, ISRO’s most powerful rocket, is known for its ability to carry large payloads into space, making it essential for missions requiring high payload capacity. In this mission, LVM3-M6 successfully placed the 6,100 kg BlueBird Block-2 satellite into Low Earth Orbit (LEO). This makes the BlueBird Block-2 the heaviest payload ever launched by the LVM3, setting a new benchmark for the rocket’s capabilities.

The satellite launch is part of a commercial mission, underlining ISRO's growing role in the international space market. The BlueBird Block-2 satellite was launched as part of a partnership between ISRO and U.S.-based AST SpaceMobile, aimed at providing global mobile broadband coverage. The satellite's primary objective is to improve communication networks by providing mobile connectivity across underserved regions, especially in remote areas. At nearly 2,400 square feet, BlueBird 6 is over three times the size and ten times the capacity of AST SpaceMobile’s six satellites currently in orbit. The satellite is designed to enable peak data rates of up to 120 Mbps directly to standard, unmodified mobile devices, supporting voice, full data, and video applications from space.

More information: 

Sriharikota is a barrier island off the Bay of Bengal coast located in the Shar Project settlement of Tirupati district in Andhra Pradesh, India. It houses the Satish Dhawan Space Centre, one of the two satellite launch centres in India (the other being Thumba Equatorial Rocket Launching Station, Thiruvananthapuram). ISRO launches satellites using multistage rockets, such as the PSLV and the GSLV, from Sriharikota. Sriharikota was selected by ISRO because of its proximity to the equator, it gives extra centripetal force from the rotation of Earth.

China continues to expand its space program with 72 launches in 2025

China continues to expand its space program with 72 launches in 2025

China’s space program has been reaching for the stars in 2025 with 72 orbital launches in the year—30% up on 2024. The country's Tiangong Space Station continued to be a major focus of activity in 2025 with the arrival of the Shenzhou-20 crew in April 2025, ready for their six-month stay. However it was not all chicken wings and steak on the China Space Station—the crew’s return to Earth was delayed after space debris hit their spacecraft.

Interstellar Comet 3I/ATLAS: Earth Flyby

Interstellar Comet 3I/ATLAS: Earth Flyby

Attention grabbing interstellar visitor 3I/ATLAS made its not-so-close flyby of our fair planet on December 19, 2025, at a distance of 1.8 astronomical units. This is about 900 light-seconds. Still, this deep exposure captures the comet from another star system as it gently swept across a faint background of stars in the constellation Leo about 4 days earlier, on the night of December 15. Though faint, colors emphasized in the image data, show off the comet's yellowish dust tail and bluish ion tail along with a greenish tinged coma. And even while scrutinized by arrays of telescopes and spacecraft from planet Earth, 3I ATLAS is headed out of the Solar System. It is presently moving outward along a hyperbolic trajectory at about 64 kilometers per second relative to the Sun, too fast to be bound the Sun's gravity.

The NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile discovered the interstellar comet 3I/ATLAS on July 1, 2025.

Comet 3I/ATLAS appears relatively normal when compared to Solar System comets, therefore providing more evidence that our Solar System is a somewhat typical one. For example, Comet 3I/ATLAS has a broadly similar chemical composition and ejected dust.

The Christmas Tree Star Cluster & Fox Fur Nebula in Monoceros

The Christmas Tree Star Cluster & Fox Fur Nebula in Monoceros

A star forming region cataloged as NGC 2264, this beautiful but complex arrangement of interstellar gas and dust is about 2,700 light-years distant in the faint but fanciful constellation Monoceros, the Unicorn. Seen toward the celestial equator and near the plane of our Milky Way galaxy, the seasonal skyscape mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dust clouds. Where the otherwise obscuring dust clouds lie close to the hot, young stars, they also reflect starlight, forming blue reflection nebulae. In fact, bright variable star S Monocerotis is immersed in a blue-tinted haze near center. Arrayed with a simple triangular outline above S Monocerotis, the stars of NGC 2264 are popularly known as the Christmas Tree star cluster. Carved by energetic starlight, the Cone Nebula sits upside down at the apex of this cosmic Christmas tree while the dusty, convoluted pelt of glowing gas and dust under the tree is called the Fox Fur Nebula. This rich telescopic frame spans about 1.5 degrees or 3 full moons on the sky top to bottom, covering nearly 80 light-years at the distance of NGC 2264.

Comet C/2023 & Orbital Sunrise | International Space Station

Comet C/2023 & Orbital Sunrise | International Space Station

C/2023 A3 (Tsuchinshan–ATLAS) is a comet from the solar system's Oort cloud discovered by the Purple Mountain Observatory east of Nanjing, China, on January 9, 2023, and independently found by the automated Asteroid Terrestrial-impact Last Alert System (ATLAS) in South Africa on February 22, 2023. ATLAS is funded by NASA's planetary defense office, and developed and operated by the University of Hawaii's Institute for Astronomy. C/2023 A3 passed perihelion (closest approach to the Sun) at a distance of 0.39 AU (58 million km; 36 million miles) on September 27, 2024.

The Oort cloud is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years).

This brief video from low-Earth orbit was captured by experienced NASA astronaut and former Expedition 71/72 flight engineer, Don Pettit. NASA astronaut Don Pettit returned to Earth on April 19, 2025, concluding a seven-month science mission aboard the International Space Station. Pettit spent 220 days in space, earning him a total of 590 days in space over the course of his four spaceflights. He orbited the Earth 3,520 times, traveling 93.3 million miles in low-Earth orbit.

The Moon+Reflection+Zodiacal Light at Orbital Sunrise | International Space Station

The Moon+Reflection+Zodiacal Light at Orbital Sunrise | International Space Station

What a beautiful Christmas from Earth orbit!

It is rare to capture four such visual elements all at once!

Expedition 74 Flight Engineer and Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui: "It's a view full of beautiful collaborations and performances . . . the Moon and its reflection & zodiacal light."

What's that strangely diffused white light? 

Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset—or just before sunrise—and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and that it slowly spirals into the Sun.

Astronauts aboard the International Space Station (ISS) experience 15 to 16 sunrises and sunsets each day due to its rapid orbit around the Earth. This occurs approximately every 45 minutes, allowing them to witness this phenomenon multiple times throughout the day.

The Swan Nebula: A Perfect Storm of Turbulent Gases | Hubble Space Telescope

The Swan Nebula: A Perfect Storm of Turbulent Gases | Hubble Space Telescope

Merry Christmas! This year, NASA has a cosmic swan 🦢 for you.

This nebula, Messier 17 (also nicknamed the Swan or Omega Nebula), was imaged by the Hubble Space Telescope. This painting-like image shows vast clouds of gas and dust illuminated by the intense radiation from young stars. The entire nebula covers about 40 light-years in total. It is a popular target for amateur astronomers. They can obtain good quality images using small telescopes.

Like the fury of a raging sea, this image from the NASA/European Space Agency Hubble Space Telescope shows a bubbly ocean of glowing hydrogen, oxygen, and sulphur gas in the extremely massive and luminous molecular nebula Messier 17. This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light-years away in the Sagittarius constellation. The colors in the image represent a variety of gases. Red represents sulphur; green, hydrogen; and blue, oxygen.

The wave-like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars that lie outside the picture to the upper left. The glow of these patterns highlights the 3D structure of the gases. The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The warmed surfaces glow orange and red in this image. The intense heat and pressure cause material to stream away from the surface, creating the glowing veil of even hotter green-colored gas that masks background structures. The pressure on the tips of the waves may trigger new star formation within them. The image, roughly three light-years across, was taken on May 29-30, 1999, with Hubble's Wide Field Planetary Camera 2.

Winter Solstice Aurora: View from Finland

Winter Solstice Aurora: View from Finland

Astrophotographer Sebastian Sainio: "The elevated solar wind put on a good show December 21st to 22nd. I took a self-portrait of myself standing on a quiet road admiring the auroras at around 1am local time."

The winter solstice marks the shortest day and longest night of the year, occurring around December 21 or 22 in the Northern Hemisphere and June 20 or 21 in the Southern Hemisphere.

What is the Winter Solstice?
The winter solstice, also known as the hibernal solstice, occurs when one of Earth's poles reaches its maximum tilt away from the Sun. This astronomical event results in the shortest period of daylight and the longest night of the year for the hemisphere experiencing winter. In the Northern Hemisphere, the winter solstice typically falls on December 21 or 22.

Vera C. Rubin Observatory 2025 Holiday Wishes!

Vera C. Rubin Observatory 2025 Holiday Wishes!


Happy Holidays from the United States National Science Foundation and Department of Energy (NSF-DOE) Vera C. Rubin Observatory in Chile!

Tarjeta de fiestas 2025 del Observatorio Rubin

¡Felices fiestas del Observatorio Rubin!

The Rubin Observatory is packed with new technology. The Simonyi Survey Telescope’s drive system, rigid design, and compact shape give it incredible speed, forming the streaks of light showcased in this image. Thanks to these features, the telescope can be ready for its next image in only five seconds—faster than any other telescope of its size. The LSST Camera, constructed by DOE’s SLAC National Accelerator Laboratory is the world’s largest digital camera. The camera is roughly the size of a small car and weighs almost 6600 lbs (3000 kg). Its size and design allow it to view vast areas of the sky, capturing 45 times the area of the full Moon in the sky with each exposure. Together, the innovative technologies in the Simonyi Survey Telescope and the LSST Camera is expected to make many discoveries.

Rubin's sensitive camera captures variations so subtle that our eyes can barely detect them when looking at the images. Rubin’s wide view and fast survey speed will give us data on far more of these stars than ever before—even those way out in the outskirts of the Milky Way—giving us a much clearer picture of what our Galaxy looks like. 

The Vera C. Rubin Observatory is located on the summit of Cerro Pachón in the Coquimbo Region, Chile, at an elevation of 2,700 meters above sea level.

Mysterious Little Red Dots of the Early Universe | James Webb Space Telescope

Mysterious Little Red Dots of the Early Universe | James Webb Space Telescope

What are these little red dots (LRDs)? No one knows. Discovered only last year, hundreds of LRDs have now been found by the James Webb Space Telescope in the early universe. Although extremely faint, LRDs are now frequently identified in deep observations made for other purposes. A wide-ranging debate is raging about what LRDs may be and what importance they may have. Possible origin hypotheses include accreting supermassive black holes inside clouds of gas and dust, bursts of star formation in young dust-reddened galaxies, and dark matter powered gas clouds. The highlighted images show six nearly featureless LRDs listed under the JWST program that found them, and z, a distance indicator called cosmological redshift. Additionally, searches are underway in our nearby universe to try to find whatever previous LRDs might have become today.

A panel of six images shows a red dot in the center of each image. The instrument that took the image is listed on each image, along with a z number that is the cosmological redshift.
