What the Universe looks like: from nearby to far away

Looking skyward fills us with wonder. Off-world, the Sun, planets, stars, and galaxies all await. Our Solar System encompasses our own cosmic backyard. Farther away, stars and star clusters abound within the Milky Way. Hundreds of billions of stars exist just within our home galaxy. Inside our Local Group, only Andromeda surpasses us in mass, size, and stars. More than 5 million light-years away, galaxies abound in groups and clusters.

fromThe Atlantic

He Won the Nobel Prize for Physics. Then He Changed His Mind.

Adam Riess discovered the universe's accelerating expansion and now contemplates potential flaws in his theory of dark energy.

Ask Ethan: Could dark energy be more negative than a cosmological constant?

The Universe will expand forever due to dark energy discovered at the end of the 20th century.

Neutrinos are still the most mysterious particle we know of

The neutrino is the most mysterious known particle and uniquely positioned to potentially solve dark matter, dark energy, and the matter–antimatter asymmetry.

Ask Ethan: Is the Hubble tension the same thing as dark energy?

Dark energy and the Hubble tension both stem from observations indicating the Universe's expansion has accelerated in recent cosmic history.

Are Black Holes Creating Dark Energy?

Black holes may produce dark energy tied to dying stars, potentially resolving discrepancies between different measurements of cosmic expansion.

How a Nearby Cosmic Void Could Be Distorting Our Understanding of the Universe

Accurate mapping of the nearby cosmos is essential because local structures and motions can bias measurements of cosmic expansion, dark energy, and the Hubble tension.

Logarithmic distance scales reveal how planetary, stellar, galactic, and cosmic‑web structures relate across enormous distances.

Ask Ethan: Is dark energy no longer a cosmological constant?

Observational evidence hints dark energy may change over time, but current data remain inconclusive and many experts still favor a constant cosmological-constant interpretation.
