With the observation of SN 2025wny, a lensed superluminous supernova, astronomy's future comes into sharp, exciting focus.

It takes a wide variety of processes in the Universe to make all the elements that populate space today. We're still discovering new ones!

Science isn't absolute. Its truths and discoveries enable us to approximate reality, but we must always remain open-minded to revisions.

The method you use to measure the expanding Universe determines which of two answers you'll get. Lensed supernovae can't resolve that issue.

Scientific truths remain true regardless of belief. These 10, despite contrary claims, remain vitally important as 2025 draws to a close.

Some vital, key ingredients must be in place for the Universe to make more matter than antimatter. The LHC took us one step closer in 2025.

As the lightest baryon in the Universe, the proton is thought by many to be eternally stable. But if it isn't, can we observe it decaying?

Finding alien Earths requires seeing Earth-sized planets at Earth-like distances from Sun-like stars. A new discovery completes the roadmap.

With a waning Moon and a denser-than-ever debris trail, 2025's Geminids might be the year's best meteor shower, and 2026's could be amazing.

We have a picture of how and when it will all come to an end. These three big ideas could still profoundly change how our cosmos evolves.

Science has assembled an incredible story outlining our Universe's whole history. Despite its unrivaled success, 9 profound gaps remain.

There are so many problems, all across planet Earth, that harm and threaten humanity. Why invest in researching the Universe?

Although American Thanksgiving only comes once a year, the scientific rules that make our Universe possible are always worth appreciating.

The far side of the Moon is incredibly different from the Earth-facing side. 66 years later, we know why the Moon's faces are not alike.

Everything ever seen — every star, mountain, and face — makes up less than 5 percent of the universe. Astrophysicist Janna Levin reminds us that the rest — dark matter and dark energy — is invisible, mysterious, and everywhere. We are the luminous exception in a universe of darkness.

Such massive, early supermassive black holes have puzzled astronomers for decades. At last, we've finally figured out how they form.

Every observation out into deep space is also a look back in time.

One side of the Moon always faces us: the near side. The "dark side" of the Moon began as a mere metaphor, but today, science can weigh in.

From white holes to dark stars and multiverses, James Riordon explores the bizarre exhibits of general relativity's "cryptozoo."

Spirals, ellipticals, and irregulars are all more common than ring galaxies. At last, we know how these ultra-rare objects are made.

Wavelengths stretch, distances grow, and temperatures cool as the Universe expands with time. How are the various cosmic parameters related?

Weird-looking galaxies, with tentacle-like tails or prominent dual streams, appear like jellyfish or bunny ears. But that’s just the start.

For over 10 billion years, the cosmic star-formation rate has been dropping and dropping. Someday, the final star in the Universe will die.

We first measured G, the gravitational constant, back in the 18th century. As the least well-known fundamental constant, can it be improved?

In 2017, a kilonova sent light and gravitational waves across the Universe. Here on Earth, there was a 1.7 second signal arrival delay. Why?

NASA’s Caleb Scharf talks with Big Think about life’s long experiment in expansion.

What if the first search for life beyond Earth actually succeeded?

Planets grow from protostellar material in disks, leading to full-grown planetary systems in time. At last, the final gap has been filled.

Until the late 20th century, there wasn't a truly universal standard. Under our current definition, everyone agrees on what "one meter" is.

Do aliens speak the same physics that we do, with similar laws, observables, and underlying mathematics. Maybe not, argues Daniel Whiteson.
