Matter and energy are the two basic components of the entire Universe. An enormous challenge for scientists is that most of the matter in the Universe is invisible and the source of most of the energy ...

In observations led by CfA scientists, NASA’s SPHEREx has mapped water, carbon dioxide, and carbon monoxide ices attached to the surface of tiny dust particles in clouds spanning hundreds of ...

The students’ presentations ranged from astrochemistry and Earth-like planet atmosphere formation to unusual movement patterns by red supergiant star Betelgeuse. Cambridge, MA (April 27, 2026) — Six ...

Astronomers at The University of New Mexico have recently published new research confirming three bodies orbiting the dynamic exoplanet system TOI-201. They include a super-earth (TOI-201 d), a warm ...

CfA Colloquia offer an opportunity for scientists, engineers, and staff to hear about topics at the forefront of astrophysical research from leaders in their field. Themes range from upcoming NASA ...

The Sun is the only star we can study in detail, providing us with the opportunity to observe stellar internal structure, magnetic fields, and atmosphere. Solar and Heliospheric Observer (SOHO), a ...

Astrophysical environments are often strikingly different from those on Earth, but there’s no direct way for astronomers to measure conditions in space. Instead, they must infer environmental ...

Mapping the structure of galaxy clusters using the hot plasma that fills the space between galaxies. Even though this plasma’s density is low, its temperature can reach hundreds of millions of degrees ...

When stars die, their fate is determined by how massive they were in life. Stars like our Sun leave behind white dwarfs: Earth-size remnants of the original star’s core. More massive stars explode as ...

Looking for hidden structures and unusual stars that reveal the Milky Way’s history. Since our galaxy grew by merging with and eating other galaxies, traces of that violent past are visible in the ...

Science isn’t merely for scientists. Understanding science is part of being a well-rounded and informed citizen. Science, technology, engineering, and mathematics (STEM) education research is ...

For a number of years, many universities have offered massive open online courses (MOOCs) in addition to traditional in-person classes. MOOCs are designed for much larger numbers of students than ...
