Older Stars Rotate Faster Than Expected

Older Stars Rotate Faster Than Expected Older stars should slow down, but new observations reveal that they have just as much of a spring in their step as their younger cousins. Astronomers suspect that complex interactions with the star’s magnetic field might be to blame. All stars spin. And all stars have magnetic fields. As […]

Charting the expansion history of the universe with supernovae

Charting the expansion history of the universe with supernovae An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match the data when a new time dependent variation is introduced. If proven correct with future, higher-quality data from the Subaru Telescope […]

Exploding Stars are Titanium Factories

Exploding Stars are Titanium Factories If you’re a fan of titanium, you should head to the nearest supernova. You’ll get more than enough of it. And its presence can help astronomers understand how supernovae work. We understand the basic picture of how the most massive stars die. Once an iron core fuses in their centers, […]

New research reveals hidden processes at work in the hearts of large stars

New research reveals hidden processes at work in the hearts of large stars Astronomers commonly refer to massive stars as the chemical factories of the Universe. They generally end their lives in spectacular supernovae, events that forge many of the elements on the periodic table. How elemental nuclei mix within these enormous stars has a […]

How Squeezable are Neutron Stars?

How Squeezable are Neutron Stars? Two neutron stars. One is 50% more massive than the other, yet they are almost exactly the same size. The results have big implications for understanding what neutron stars are really made of. In 2019 a team of astronomers led by Thomas Riley, a postdoctoral researcher, and Anna Watts, a […]

Scientists invent method for predicting solar radio flux for two years ahead

Scientists invent method for predicting solar radio flux for two years ahead Since the launch of Sputnik, the Earth’s first artificial satellite, in 1957, more than 41,500 tons of manmade objects have been placed in orbit around the sun, the Earth, and other planetary bodies. Since that time, the majority of objects, such as rocket […]

Following the Moon for Amazing May Astronomy

Following the Moon for Amazing May Astronomy The May Moon Meets Venus and Mercury, at dusk en route to eclipse season and more. Wonder where all the solar system action is hiding? While the dusk sky may seem devoid of planets (save for Mars), that’s all about to change this evening. The watch-phrase for astronomy […]

Astronomers detect substellar companion of HD 47127

Astronomers detect substellar companion of HD 47127 Using the Harlan J. Smith Telescope, astronomers have discovered that the star HD 47127 has a substellar companion. The newly identified object, designated HD 47127 B, appears to be a brown dwarf or a brown dwarf binary. The finding is reported in a paper published May 4 on […]
