NASA's Artemis 2 moon launch may be visible from Florida and southern Georgia today. Here's when to look

Here's where you need to be to see the Artemis 2 moon rocket launch with your own eyes.

Watch Artemis 2 fly through space in real time with this telescope livestream tonight

A Virtual Telescope Project livestream aims to track NASA's Artemis 2 Orion spacecraft — here's how to watch it as it travels through space.

Exploding Primordial Black Holes Might Have Reshaped the Early Universe - And Created All Matter As We Know It

The early universe is absolutely so far outside our understanding of how the world works it's hard to describe in words. Back then, the cosmos wasn’t filled with stars and galaxies but with a boiling soup of quarks and gluons, with a few microscopic black holes thrown in, occasionally detonating like depth charges. That’s the early universe theorized by a new paper, available in pre-print from arXiv, from researchers at Vrije Universiteit Brussel and MIT anyway.

Saturn's magnetic field is curiously warped, and one of its moons may be to blame

"A better understanding of Saturn’s environment is especially urgent now as plans for our return to Saturn and its moon Enceladus start to be developed."

NASA set to launch Artemis 2 moon mission today, the 1st crewed lunar flight since 1972

NASA plans to make history today (April 1) with the launch of Artemis 2, the first crewed moon mission since Apollo 17 in 1972.

Christine Klein takes up duty as acting Director of Controlling, Finance and Operational Procurement

Christine Klein took up duty as acting Director of Controlling, Finance and Operational Procurement (D/CFO) at the European Space Agency on 1 April 2026. She will lead the newly established directorate during its consolidation.

Géraldine Naja takes up duty as Director of Space Transportation

Géraldine Naja took up duty as Director of Space Transportation (D/STS) at the European Space Agency on 1 April 2026. She will continue to serve as head of her former directorate, now called the Commercialisation and Industry Partnership directorate (D/CIP), as acting director.

Mercury Scout Mission Concept with Solar Sail Propulsion

The planet Mercury is the closest planet to the Sun, and also the most difficult for spacecraft to visit and explore. This is because as spacecraft get closer to Mercury, the Sun’s enormous gravity pulls in the spacecraft, greatly increasing its speed and making it hard to slow down without large amounts of fuel. But what if a spacecraft could both travel to and explore Mercury without fuel? This could drastically reduce mission costs while delivering impactful science.

KYTHERA Mission Concept Targets 200-Day Mission to Venus Surface

The planet Venus is often called “Earth’s twin” due to the similar sizes, but the reality couldn’t be farther from the truth. Unlike Earth, which is hospitable to an estimated billions of lifeforms, Venus is not hospitable to life as we know it, at least on its surface. This is because the surface of Venus not only experiences an average temperature of 464 degrees Celsius (867 degrees Fahrenheit), but it also has crushing pressures approximately 92 times of Earth, or equivalent to approximately 1 kilometer (3,000 feet) below the ocean. These extreme surface conditions are why the longest spacecraft to survive on the Venusian surface is just over two hours.

Optical Fiber Arrays May Unlock Mysteries Of The Moon’s Deep Interior

With tomorrow’s launch of the Artemis II mission to the moon, NASA’s focus on our natural satellite is again gaining traction. To that end, two recent papers in the journals Earth and Space Science* and Icarus* point out how ordinary fiber optic technology could be deployed on the lunar surface to detect our ancient neighbor’s seismic activity.

Orbits of the Planets

Introduction to Planetary Orbits

The paths that planets take as they revolve around the Sun are known as orbits. In our solar system, all eight planets—Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune—follow distinct, elliptical (oval-shaped) paths around the Sun. This motion is governed primarily by the law of universal gravitation, as famously described by Sir Isaac Newton, and the geometrical laws of planetary motion formulated by Johannes Kepler.

This star-forming galaxy is blowing out powerful winds topping 2 million mph

NASA's XRISM X-ray spacecraft has clocked 2 million mph winds ripping out of a distant galaxy bursting with star formation.

Yes, NASA's launching Artemis 2 astronauts to the moon on April Fools' Day. It's not a joke.

NASA is hoping for a historic moon launch, not a punchline on April 1.

Comet MAPS faces a make-or-break moment as it dives toward the sun on April 4 — could it shine in the daytime sky?

Comet MAPS is about to face its ultimate test as it sweeps just 101,000 miles above the sun's surface.

A New Theory Connects Early Cosmic Inflation and Quantum Gravity

Modern cosmology is built upon three theoretical pillars: special relativity, Newtonian gravity, and quantum mechanics. Each is supported by a wealth of experimental evidence, but each describes the physical world in a way that contradicts the other two.
