A supermassive black hole, weighing as much as 20 million Suns, has left behind a 2,00,000-light-year-long condensed trail of newborn stars, twice the diameter of the Milky Way galaxy, in its wake, according to the National Aeronautics and Space Administration (NASA), US.

Captured accidentally by NASA‘s Hubble Space Telescope, the black hole was seen racing through the intergalactic space so fast that, within our solar system, it could travel from Earth to the Moon in 14 minutes.

“We think we’re seeing a wake behind the black hole where the gas cools and is able to form stars. So, we’re looking at star formation trailing the black hole,” said Pieter van Dokkum of Yale University in New Haven, Connecticut, US.

“What we’re seeing is the aftermath. Like the wake behind a ship, we’re seeing the wake behind the black hole,” said van Dokkum.

The researchers have published their paper in The Astrophysical Journal Letters.

They said that the black hole lies at one end of the column, at the other end of which lies its parent galaxy. They think that the gas is being ‘shocked’ and heated from the motion of the black hole hitting the gas, or it could be radiation from an accretion disk around the black hole.

“This is pure serendipity that we stumbled across it,” van Dokkum added. He was looking for globular star clusters in a nearby dwarf galaxy.

“I was just scanning through the Hubble image and then I noticed that we have a little streak. I immediately thought, ‘oh, a cosmic ray hitting the camera detector and causing a linear imaging artifact.’ When we eliminated cosmic rays we realized it was still there. It didn’t look like anything we’ve seen before,” said van Dokkum.

Van Dokkum and his team followed up the sight with spectroscopy with the W M Keck Observatories in Hawaii. The star trail being “quite astonishing, very, very bright and very unusual” made them conclude that they were looking at the aftermath of a black hole flying through a halo of gas surrounding the host galaxy.

Astronomers suspect this phenomenon to likely be the result of multiple collisions of supermassive black holes, the first two having perhaps merged 50 million years ago. Brought together closer at their centres, they whirled around each other as a binary black hole, they said.

Then came another galaxy with its own supermassive black hole, mixing up the three to form a chaotic and an unstable configuration. One of the black holes robbed momentum from the other two black holes and got thrown out of the host galaxy, they said.

Following this, the remaining binary system of black holes shot off in the opposite direction, they said.

There is a feature seen on the opposite side of the host galaxy that might be the runaway binary black hole. Circumstantial evidence for this is that there is no sign of an active black hole remaining at the galaxy’s core, they said.

The next step, they said, would be to do follow-up observations with NASA’s James Webb Space Telescope and the Chandra X-ray Observatory to confirm the black hole explanation.

NASA’s New Missions Will Map the Sun and the Cosmos

Two NASA missions aimed at advancing space research are scheduled for launch aboard a SpaceX Falcon 9 rocket on March 2 from Launch Complex 4E at Vandenberg Space Force Base in California. The spacecraft, PUNCH and SPHEREx, have been designed for separate but complementary scientific objectives. While PUNCH will focus on the dynamics of the Sun’s corona and solar wind, SPHEREx will survey the broader universe using infrared observations. This dual launch, facilitated under NASA’s Launch Services Program, is expected to enhance understanding of cosmic evolution and space weather phenomena.

PUNCH to Study Solar Wind and Space Weather

As reported by Space.com, according to NASA, the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission consists of four small satellites designed to create three-dimensional images of the Sun’s outer atmosphere. These satellites will use polarized light to track solar events such as coronal mass ejections (CMEs), helping scientists determine their trajectories and potential impacts on Earth. Speaking to Space.com, Nicholeen Viall, PUNCH mission scientist at NASA’s Goddard Space Flight Center, stated that the mission is expected to provide significantly improved resolution compared to previous heliophysics missions like STEREO.

SPHEREx to Map the Universe in Infrared

As per NASA, the Spectro-Photometer for the History of the Universe, Epoch of Reionisation, and Ices Explorer (SPHEREx) will conduct an extensive infrared survey of the entire sky every six months. Unlike the James Webb Space Telescope, which captures highly detailed images of specific regions, SPHEREx is designed to generate broad cosmic maps in 102 wavelengths. In a statement to Space.com, Phil Korngut, SPHEREx instrument scientist at the California Institute of Technology, noted that the data will contribute to research on cosmic inflation, galaxy formation, and the origins of water in planetary systems.

Both missions are expected to play a crucial role in expanding current knowledge of space phenomena, with their launch anticipated to provide valuable insights into both solar and cosmic environments.

SpaceX Falcon 9 Launches Athena Lander, NASA's Lunar Trailblazer to Moon

A SpaceX Falcon 9 rocket lifted off from Kennedy Space Center on February 26, 2025, carrying the Athena lunar lander and NASA’s Lunar Trailblazer orbiter. The launch, which took place at 7:16 p.m. EST from Launch Complex-39A, marked a significant step in lunar exploration. Athena, developed by Intuitive Machines, is designed to investigate lunar water ice deposits, while Lunar Trailblazer will study similar phenomena from orbit.

Scientific Goals and Technology

As per reports, according to NASA, Athena is equipped with ten scientific instruments, including the Polar Resources Ice Mining Experiment 1 (PRIME-1). The experiment consists of the Regolith Ice Drill for Exploring New Terrain (TRIDENT) and the Mass Spectrometer observing lunar operations (MSolo), both of which will work to extract and analyse samples from beneath the lunar surface. These investigations aim to provide critical data on the presence of water ice, supporting future in-situ resource utilisation (ISRU) efforts.

Lunar Trailblazer, an orbiter developed by NASA, will complement Athena’s findings by mapping water ice deposits across the lunar surface. Scientists have stated that its data will enhance the understanding of lunar ice distribution, particularly in the Mons Mouton region, where Athena is expected to land.

Landing Plans and Exploration Vehicles

Reports indicate that Athena will reach lunar orbit in four to five days and attempt a landing between 1.5 and three days after that. The mission will last approximately ten Earth days. To extend its exploration capabilities, Athena carries two secondary vehicles: MAPP, a rover designed by Lunar Outpost, and Grace, a hopping robot developed by Intuitive Machines. Grace will explore shadowed craters inaccessible to wheeled vehicles, while MAPP will establish a lunar cellular network using the Lunar Surface Communications System (LSCS) developed by Nokia Bell Labs.

Challenges and Expectations

This mission follows Intuitive Machines’ IM-1 mission, which achieved the first soft lunar landing by a private company but encountered a landing issue that affected data transmission. Trent Martin, Senior Vice President of Space Systems at Intuitive Machines, stated to Space.com that improved landing accuracy is a primary focus for IM-2.

NASA’s contract for IM-2 was initially valued at $47 million but increased to $62.5 million due to additional requirements, including temperature data collection. Reports suggest that Athena and Lunar Trailblazer are part of a broader lunar exploration effort, joining missions such as Firefly Aerospace’s Ghost Riders in the Sky and ispace’s Resilience lander, both launched earlier in 2025.

Scientists Find a New Way To Turn Stale Bread Into Carbon Electrodes

A team of engineers has introduced two innovative techniques for shaping carbon electrodes derived from bread. The methods, which build upon previous research, enable the formation of electrodes in precise and sturdy forms. These advancements could enhance the sustainability of electrode production by utilising stale bread, a commonly wasted food item. The process involves heating bread at high temperatures in an oxygen-free environment, converting it into a carbon-based material suitable for applications such as desalination systems. The research aims to refine this process for potential large-scale production, offering an eco-friendly alternative for carbon electrode manufacturing.

New Techniques for Molding Carbon Electrodes

According to the study published in Royal Society Open Science, the research was conducted by David Bujdos, Zachary Kuzel and Adam Wood from Saint Vincent College and the University of Pittsburgh. The team built upon earlier efforts by Adam Wood, who had previously demonstrated that stale bread could be used to produce carbon electrodes due to its high carbon content.

The latest development introduces two techniques that allow for shaping the electrodes into desired forms. The first method involves compressing bread using a 3D-printed mold before subjecting it to the heating process. This technique enables the formation of precise electrode shapes. In a test, a zigzag mold was used to demonstrate its effectiveness.

The second method requires blending bread with water before shaping it manually. Once formed, the material is dried and carbonised in an oven. While this approach provides less precision, the resulting electrodes are reportedly more durable.

Potential for Sustainable Electrode Production

As per reports, the researchers believe these methods could contribute to the development of a low-cost capacitive desalination system. The aim is to create an environmentally friendly solution that reduces food waste while addressing water purification challenges. Efforts are underway to refine the process and explore possibilities for large-scale implementation.
