Learn how scientists measure space weather using satellites, ground observatories, and key indices that track solar storms, geomagnetic activity, and radiation risk.
Scientists search for methane on Mars using orbiters, rovers, and telescopes. Here is how those measurements work and why the results remain debated.
What is a Starburst Galaxy? A starburst galaxy is a type of galaxy that experiences an exceptionally high rate of star formation. This rapid star formation is typically concentrated in the central regions of the galaxy, leading to a burst of new stars being born. Starburst galaxies are characterized by their intense luminosity and high … Read more
