Imagine being trapped inside a small sphere made of fabric with a tiny window and an air tank, suspended from the Canadarm. If the sphere moves, you will see the Earth, the damaged Space Shuttle and the Earth again. This is what NASA’s Personal Rescue Enclosure (PRE) was designed for. The PRE or rescue ball

A team of researchers from the Brera Astronomical Observatory in Italy and the University of Oxford in the UK have found a dead star moving away from its birth supernova, leaving a comet-like trail of radio emission. The star, named PSR J1914+1054g, is only the fourth known of its kind: a radio pulsar kicked at

Jupiter’s alternating bands of dark and light clouds have mystified scientists for years. However, a team of scientists from Japan, Spain, and the UK now think they have figured out the reason for the cyclic variations in Jupiter’s stripes. After studying data on Jupiter’s magnetic field collected by the Juno probe, the team suggests that

Uranus, the seventh planet from the sun, takes 84 years to orbit it. Due to this extended orbit, the last time Uranus’s north polar region was visible from Earth, radio telescope technology was in its early stages. However, the past few years have seen scientists using radio telescopes like the Very Large Array (VLA) to

Astrophysicists have long been intrigued by the nature of the first stars in the universe, which have left only traces of their presence. However, evidence traced in images from the James Webb Space Telescope now suggests that after the appearance of the first stars, there were fusion-powered balls of heat and fury, known as “chonker”

An astronomer from South Korea has recently reported that a sunspot four times the size of Earth is lined up with the Sun, and it is so large that it could be seen with the naked eye provided that the observer has the appropriate equipment to observe it safely. The astronomer has advised amateur astronomers

The Solar System is abundant in water, with planets and moons loaded with it, and comets from the far reaches carrying it. However, while water ice has been detected in the asteroid belt, its vapor has been strangely missing until now. But thanks to the James Webb Space Telescope (JWST), scientists can now confirm that

Betelgeuse, the red giant star, has been exhibiting unusual behavior since the Great Dimming that occurred in 2019 and early 2020. The fluctuations in brightness that were a regular occurrence have changed, and the star has become uncharacteristically bright. Currently, Betelgeuse is at 142 percent of its normal brightness, with a steady upward trend for

Satellites have traditionally been made of metal but a new project called LignoSat, by a team of Japanese researchers, has tested magnolia wood as a housing material for satellites. Wood has several advantages over metal, such as flexibility, strength, and relatively lightweight. Moreover, when metal enclosures burn up during reentry, aluminum shavings remain as space

The Daniel K. Inouye Solar Telescope has provided incredible, new images of the Sun, revealing intricate details of the solar atmosphere with a resolution of around 20 kilometers. The telescope has captured images of sunspots, revealing the roiling convective cells, and the motion of plasma. In addition, the telescope’s observations provide a glimpse of the

Astronomers have imaged a radiation belt around an extrasolar object for the first time. The object is a red dwarf star named LSR J1835+3259, which has about 77 times the mass of Jupiter and sits some 20 light-years away. This discovery is significant because all planets in our Solar System with global magnetic fields have

A recent study published in Geophysical Research Letters aimed to answer the question of how thick Mars’ crust is. The study reported on data from a magnitude 4.7 marsquake recorded in May 2022 by NASA’s InSight lander, which is the largest quake ever recorded on another planetary body. The data helped estimate Mars’ global crustal

Supermassive black holes (SMBHs) at the center of active galactic nuclei (AGNs), also known as quasars, emit powerful space winds known as ultra-fast outflows (UFOs). These winds move at relativistic speeds close to the speed of light and regulate the behavior of SMBHs during their active phase. These emissions are believed to fuel the process

Saturn’s rings are one of the most iconic features of the Solar System, but a new study suggests their time is limited. The rings are estimated to be between 100 million and 400 million years old, making them a recent addition to the Solar System and a fraction of the age of Saturn itself. The

NASA has been working on an AI-based early warning system for solar storms, which could provide the world with a 30-minute notice before a potentially devastating event strikes. Utilizing AI models to analyze solar storm data, the system aims to predict the severity and impact of a solar storm on Earth. Challenges and Solutions One
