Record-breaking radio burst traces back to universe's early star-forming era
Astronomers have measured the distance to the most remote fast radio burst ever recorded, FRB 20240304B, which left its source when the universe was about 3 billion years old. The James Webb Space Telescope traced the millisecond-long burst to a small, actively star-forming dwarf galaxy — not the large, mature galaxy researchers expected.
How Satellites Work: Orbits, Signals and Global Connectivity Explained
Satellites stay in orbit because their forward speed balances Earth's gravity, and the altitude chosen determines what job a satellite can do. Low orbits give sharp images and short delays, geostationary orbits give constant coverage of one region, and medium orbits power global navigation — each linked to ground stations by radio signals regulated through an international frequency system.
How space telescopes see what ground observatories cannot
Space telescopes orbit above Earth's atmosphere, which blocks or distorts most infrared, ultraviolet and X-ray light before it reaches the ground. By operating outside that barrier, observatories such as Hubble, Webb, Gaia and Chandra each capture a different slice of the electromagnetic spectrum, and together they build a more complete picture of stars, galaxies and the early universe.
How to Watch a Meteor Shower: Best Times, Spots and Techniques
Meteor showers are best seen with the naked eye, from a dark location, in the hours between midnight and dawn when a shower's radiant climbs highest in the sky. Checking the Moon phase, letting your eyes adapt to the dark, and looking slightly away from the radiant are the steps experts most often repeat.
How to Start Stargazing: A Beginner's Guide to Observing Planets and Stars
Beginners can start observing the night sky with no equipment at all: let your eyes adjust to darkness for at least 15-20 minutes, learn to tell planets from stars by their steady (non-twinkling) light, and use a star chart or app before buying any gear. Binoculars, not a telescope, are the recommended first upgrade, according to NASA and EarthSky.
How Radio Telescopes Detect Signals From Deep Space
Radio telescopes collect extremely faint radio waves with large dishes or networks of antennas, then amplify and combine the signals—sometimes linking instruments across continents with atomic-clock timing—to reveal details invisible to ordinary telescopes. This approach has produced the first image of a black hole, found more than a thousand pulsars with a single dish, and caught hundreds of split-second fast radio bursts.
How Stars Form and Evolve: The Science of the Stellar Lifecycle
Stars form when gravity collapses cold clouds of gas and dust until a core reaches about 10 million Kelvin, hot enough to ignite hydrogen fusion. From there, a star's mass determines everything else: how long it shines, how it dies, and whether it leaves behind a white dwarf, a neutron star, or a black hole.
How Rockets Work: Thrust, Propulsion Systems and Orbital Mechanics Explained
Rockets move by expelling exhaust in one direction so the vehicle is pushed in the other, under Newton's third law of motion. Thrust depends on how much exhaust mass flows out per second and how fast it leaves the nozzle, while staying in orbit depends on balancing forward speed against the pull of gravity. Multistage designs and, for some missions, electric propulsion are used to manage the enormous amount of propellant spaceflight requires.
How Astronauts Train, Prepare for Missions and Live in Space
Astronaut training is a multi-year process that starts with a selection screening for education, experience and physical fitness, then moves into years of ground training before any flight. According to NASA and the European Space Agency (ESA), candidates learn spacecraft systems and practice spacewalks underwater, and ESA candidates also study Russian, while life aboard the International Space Station (ISS) runs on a fixed daily schedule of work, exercise and sleep.
How Black Holes Form, What They Are, and What They Reveal About the Universe
A black hole is a region of space where gravity is so strong that nothing, not even light, can escape once it crosses the event horizon. Most form when a massive star runs out of nuclear fuel and its core collapses; supermassive versions grow at galaxy centers over billions of years. Direct images and gravitational-wave detections have confirmed their existence and tested Einstein's general relativity.
What Are Fast Radio Bursts? The Mystery Millisecond Signals From Deep Space
Fast radio bursts (FRBs) are millisecond-long flashes of radio energy from distant galaxies, first identified in 2007 and still not fully explained. Interest has risen after astronomers used the MeerKAT telescope and the James Webb Space Telescope to trace the most distant FRB yet, a signal that traveled over 10 billion years to reach Earth.
What Are Asteroids? Formation, Composition and How to Spot One
Asteroids are rocky remnants left over from the formation of the solar system about 4.6 billion years ago, mostly orbiting the Sun between Mars and Jupiter, according to NASA. They range from Vesta, roughly 530 kilometers across, down to boulder-sized rocks, and amateur astronomers can spot the brighter ones with binoculars or a small telescope by watching them shift against background stars over a night or two.
How to Watch Meteor Showers and Comets: A Practical Stargazing Guide
No telescope is needed to watch a meteor shower — NASA says simply lying down away from city lights is enough. Comets are harder to spot and usually require binoculars or a small telescope, according to Celestron and the American Meteor Society. This guide lays out the timing, gear and viewing techniques recommended by these sources for both.
SpaceX Dragon Crew-12 Completes Deorbit Burn, Splashes Down Off California
NASA's SpaceX Crew-12 mission ended on October 8, 2026, when the Crew Dragon capsule Freedom completed its deorbit burn and splashed down in the Pacific Ocean off the California coast at 11:34 a.m. EDT. The four-person crew — two NASA astronauts, one ESA astronaut and one Roscosmos cosmonaut — had spent 237 days aboard the International Space Station.
Why Mars Has a Blue Sunrise: NASA's Curiosity Image Explained
NASA's Curiosity rover photographed a rare blue-tinted Martian dawn over wind-carved cliffs on Mount Sharp on August 11, 2026, and released the image on October 6, 2026. The unusual colors are not a camera trick but a real effect of how Martian dust scatters sunlight — the opposite of what happens on Earth.
World Space Week 2026: 'Rocket Revolution' Theme Marks Wider Access to Space
World Space Week 2026 runs from October 4 to 10 under the theme "Rocket Revolution," marking how reusable rockets and commercial launch providers are lowering the cost of reaching orbit. The UN-recognised observance includes more than 50,000 events in over 100 countries, organized by the World Space Week Association with UN backing.
Orbital Mechanics Explained: How Planets Orbit the Sun
Planets orbit the Sun in elliptical paths dictated by gravity, moving faster when close to the Sun and slower when far away, under rules first described by Johannes Kepler and later explained by Isaac Newton's law of gravitation. Saturn's October 2026 opposition, when Earth passes between the Sun and Saturn, is a direct real-world example of these mechanics in action.
Saturn at Opposition on October 4, 2026: When and How to Watch It
Saturn reaches opposition on October 4, 2026, at about 12:00 UTC, when Earth passes directly between the Sun and the planet. This makes Saturn visible all night at its brightest and largest apparent size for the year, rising at sunset in the constellation Cetus. No special equipment is required to spot it, though binoculars and a small telescope reveal far more.
A Beginner's Guide to Spotting and Identifying Planets in the Night Sky
Five planets — Mercury, Venus, Mars, Jupiter and Saturn — are visible to the naked eye, and the simplest trick to find them is that planets shine with a steady light while stars twinkle. This guide explains where to look, how to tell the planets apart, and what free tools make it easier, using methods described by NASA's Jet Propulsion Laboratory and planetarium educators.
How Supernovae Form: The Physics Behind the Universe's Biggest Explosions
A supernova is the explosive death of a star, triggered either by the collapse of a massive star's iron core or by a runaway nuclear reaction on a white dwarf. The blast can briefly outshine entire galaxies, forge new elements, and leave behind a neutron star or black hole.
How Space Telescopes Work: Mirrors, Wavelengths and Seeing Cosmic History
Space telescopes gather light with mirrors far above Earth's atmosphere, which otherwise blurs images and blocks ultraviolet and infrared wavelengths. Different observatories are built for different kinds of light — Hubble for visible/UV, Webb for infrared, Chandra for X-rays — and because light takes time to travel, these instruments let astronomers see galaxies as they looked billions of years ago.
How Satellites Shape Daily Life: From GPS Navigation to Weather Forecasts
Satellites orbiting Earth provide the positioning signals behind GPS navigation and the imagery behind daily weather forecasts. A combination of medium-Earth-orbit navigation satellites and geostationary or polar-orbiting weather satellites now underpins everyday tools from smartphone maps to storm warnings.
Black Holes Explained: How They Form and How Astronomers Detect Them
A black hole is a region of space where gravity is so strong that nothing, not even light, can escape once it crosses the event horizon. Astronomers cannot see black holes directly, so they infer their presence from effects on nearby matter, light and space-time — through accretion disks, orbiting stars, and ripples called gravitational waves. Two landmark observations, the 2015 LIGO gravitational-wave detection and the 2019 Event Horizon Telescope image of M87, turned the concept from theory into direct evidence.
SpaceX Crew-13 docks at ISS as Jessica Watkins becomes first Black woman to command a crew in orbit
A SpaceX Dragon carrying four astronauts docked at the International Space Station on October 1, 2026, in the fastest U.S. crewed flight to the ISS on record. Commander Jessica Watkins became the first Black woman to lead a crew to the station, while France's Sophie Adenot, part of the outgoing Crew-12, is set to return to Earth in the coming days after an eight-month mission.
How Black Holes Form and Why They Are the Universe's Most Extreme Objects
Black holes form mainly when a massive star's core collapses after a supernova, or when the universe's first instants left ultra-dense pockets of matter. NASA and ESA describe four classes — stellar, intermediate, supermassive and primordial — defined chiefly by mass. Their defining trait is an event horizon: a boundary beyond which not even light can escape.
What a September 28 Solar Eruption Means for Earth on October 2, 2026
A coronal mass ejection (CME) released by a solar filament eruption on September 28, 2026, is reaching Earth on October 2, prompting NOAA's Space Weather Prediction Center to issue a G1-level "minor" geomagnetic storm watch, the lowest tier on its five-step scale. Forecasters expect only small effects on satellites, GPS and radio signals, while the storm could push aurora sightings farther south than usual.
How to Observe Saturn's Rings at the October 4 2026 Opposition
Saturn reaches opposition on October 4, 2026, when it is closest to Earth, brightest, and visible all night. At magnitude +0.3 in the constellation Cetus, the planet can be spotted with the naked eye, while binoculars or a small telescope reveal its rings, tilted about 7 to 7.5 degrees toward Earth.
