Sunday (March 2) is shaping up to be a delightful day for space explorers, as not one but two major NASA missions are expected to take to the skies — and interestingly, though the spacecraft associated with these missions are pretty different from one another, you might say they all have the same profession: cosmic … Read more
NASA’s latest space telescope, SPHEREx, scheduled for launch on 28 February in tandem with another mission called PUNCH, has been hailed for both the colour range of the images it will produce and its ability to “peer back” to the first second after the Big Bang. What the telescope will actually do, however, is somewhat … Read more
The Lucy spacecraft, en route to the Trojan asteroids around Jupiter, first has its sights set on a main-belt asteroid, Donaldjohanson. NASA shared this view of the targeted asteroid on February 25, 2025. Image via NASA/ Goddard/ SwRI/ Johns Hopkins APL.

A planet’s history is told in its ancient rock. Earth’s oldest rocks are in the Canadian Shield, Australia’s Jack Hill, the Greenstone Belts in Greenland, and a handful of other locations. These rocks hold powerful clues to our planet’s history. On Mars, the same holds true. That’s why NASA’s Perseverance rover is revisiting some of … Read more
We now have a fine opportunity to view the planet that many astronomy guide books refer to as the most difficult of the naked-eye planets to see. The planet in question is Mercury. Beginning now and running through the end of the second week of March, this somewhat overgrown version of the moon will have … Read more
NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is widely known as the nation’s largest rocket propulsion test site. More than 35 years ago, it also served as a hands-on classroom for NASA engineers seeking to improve the efficiency of space shuttle main engines. From 1988 to the mid-1990’s, NASA Stennis engineers operated a … Read more
How can we explore Saturn’s moon, Enceladus, to include its surface and subsurface ocean, with the goal of potentially discovering life as we know it? This is what a recent study presented at the American Geophysical Union (AGU) 2024 Fall Meeting hopes to address as a team of students and researchers proposed the Thermal Investigation … Read more
Galaxies, planets, black holes: to most people, everything about our Universe sounds and feels enormous. But while it’s true that much of what happens millions of light years away is large, there are also processes happening at the quantum end of the scale. That’s the branch of science which explains how nature works at very … Read more
Some exoplanets have characteristics totally alien to our Solar System. Hot Jupiters are one such type. They can have orbital periods of less than 10 days and surface temperatures that can climb to well over 4,000 K (3,730 °C or 6,740 °F). Unlike any planets in our system, they’re usually tidally locked. Astronomers probed the … Read more
The concept of the “great filter” to explain why so far we seem to be alone in the universe is based on erroneous assumptions, according to a new model that describes how life on Earth evolved in step with changing geobiological conditions rather than through a series of improbable events. “We’re arguing that intelligent life … Read more
