Researchers from Johns Hopkins University and other institutions have found that, on average, the temperature of galaxy clusters today is 4 million degrees Fahrenheit. That is 10 times hotter than 10 billion years ago, and four times hotter than the Sun’s outermost atmosphere called the corona. The findings are published in the Astrophysical Journal.

Study: Dying Stars Breathe Life Into Earth
As dying stars take their final few breaths of life, they gently sprinkle their ashes into the cosmos through the magnificent planetary nebulae. These ashes, spread via stellar winds, are enriched with many different chemical elements, including carbon.
Findings from a study published today in Nature Astronomy show that the final breaths of these dying stars, called white dwarfs, shed light on carbon’s origin in the Milky Way.
Dark Matter May Be Older Than The Big Bang, Study Suggests
Dark matter, which researchers believe make up about 80% of the universe’s mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new Johns Hopkins University study now suggests that dark matter may have existed before the Big Bang.
Johns Hopkins Scientist Proposes New Definition of a Planet
Pluto hogs the spotlight in the continuing scientific debate over what is and what is not a planet, but a less conspicuous argument rages on about the planetary status of massive objects outside our solar system. The dispute is not just about semantics, as it is closely related to how giant planets like Jupiter form. Johns Hopkins University astrophysicist Kevin Schlaufman aims to settle the dispute.
Johns Hopkins Physics Fair Returns to Homewood Campus
The Department of Physics and Astronomy at Johns Hopkins University will host its 12th annual Physics Fair from 11 a.m. to 5:30 p.m. on Saturday, April 25. The fair coincides with the university’s annual Spring Fair celebration on the Homewood campus.
