Discover why Earth's farthest distance from the sun coincides with summer heat, then grab your binoculars for a week of ...

An engrossing look at how knowledge has grown alongside our technologies, and how we might unlock the puzzles of the Universe ...

Astronomers have worked for years to assemble this “cosmic distance ladder,” and they're constantly trying to calibrate it ever more finely.

The cosmic distance ladder is a method used by astronomers to measure distances in the universe. It relies on a series of techniques, each calibrated by the previous one, allowing us to move from ...

asked Scolnic. So that its results are truly unbiased, DESI builds its own cosmic distance ladder from scratch, rather than relying on previous measurements, with one exception.

A new measurement confirms what previous — and highly debated — results had shown: The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our ...

These involve building a cosmic ‘distance ladder’. Nasa/EsaSA/A. Feild (STScI) Just as Slipher did a century ago, recession speeds can be readily measured using spectroscopy.

New James Webb Space Telescope results have revealed that there may not be a Hubble tension after all. But contradictions ...

(via Be Smart) Since the time of the ancient Greeks, scientists have been constructing a cosmic measuring tape to measure the universe from our own backyard all the way to its ever-expanding edge: the ...

The cosmic distance ladder is the world’s longest ruler, built to measure the universe. Since the time of the ancient Greeks, scientists have been constructing a cosmic measuring tape to measure ...

The cosmic distance ladder could soon have another rung. In around 5 billion years, the sun will run out of the fuel needed for nuclear fusion in its core. This will cause its inner core to ...
