"The Hubble tension is now a Hubble crisis." The mystery of the Hubble tension has deepened with the startling finding that the Coma Cluster of galaxies is 38 million light-years closer than it should ...
astronomers can chain Cepheid readings into a "cosmic distance ladder" to peer deeper into the universe's past. But this is where the headache begins. Using the European Space Agency's Planck ...
Using this high-precision measurement as a first rung, the team calibrated the rest of the cosmic distance ladder. They arrived at a value for the Hubble constant of 76.5 kilometers per second per ...
This uniformity means Type Ia supernovas are often referred to as "standard candles," serving as a vital rung on the "cosmic distance ladder." Usually, it is difficult to tell if an astronomical ...
To measure this expansion, scientists use a cosmic distance ladder. This method relies on celestial objects, such as Type Ia supernovae, to estimate distances in the universe. Scolnic's team used data ...
All of these were based on the cosmic distance ladder, which uses a series of observations to calculate ever greater cosmic distances, each building on the previous method. But in the past few ...
the team was then able to recalibrate the so-called cosmic distance ladder and arrived at a value of 76.5 km/sec/Mpc for the so-called Hubble constant. This is once again considerably higher than ...
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. This is why its ...
