A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries. However, only a handful of white dwarf binaries are known with orbital periods less than one hour in the Milky Way—a galaxy made up of two hundred billion stars—and most have been discovered by Kilic and his colleagues.

KENNEDY SPACE CENTER, FL – Today marked the end of an era for NASA as the last of the agency’s next generation Tracking and Data Relay Satellites (TRDS) that transmit the critical science data and communications for the Hubble Space Telescope and human spaceflight missions to the International Space Station, successfully rocketed to orbit this morning, Fri. Aug 18 from the Florida Space Coast.

Dim objects called brown dwarfs, less massive than the sun but more massive than Jupiter, have powerful winds and clouds–specifically, hot patchy clouds made of iron droplets and silicate dust. Scientists recently realized these giant clouds can move and thicken or thin surprisingly rapidly, in less than an Earth day, but did not understand why. […]Read More
A team of scientists from Russia and China has developed a model explaining the nature of high-energy cosmic rays (CRs) in our galaxy. These CRs have energies exceeding those produced by supernova explosions by one or two orders of magnitude. The model focuses mainly on the recent discovery of giant structures called Fermi bubbles.

An international team of space scientists has found evidence of what they believe is a remnant of a type Iax supernova—a white dwarf moving in a way that suggests it was blown across part of the universe by the power of a thermonuclear explosion. In their paper published in the journal Science, the team describes their study of the star and why they believe it is the remains of an Iax supernova. […]Read More
I’ve often been asked the question, “Can the astronauts on the Space Station see the stars?” Astronaut Jack Fischer provides an unequivocal answer of “yes!” with a recent post on Twitter of a timelapse he took from the ISS. Fischer captured the arc of the Milky Way in all its glory, saying it “paints the heavens in a thick coat of awesome-sauce!” […]Read More

KENNEDY SPACE CENTER, FL – The last of NASA’s next generation Tracking and Data Relay Satellites (TRDS) that looks like a giant alien fish or cocooned creature but actually plays an absolutely vital role in relaying critical science measurements, research data and tracking observations gathered by the International Space Station (ISS), Hubble and a plethora of Earth science missions is poised for blastoff Friday, Aug. 18, morning from the Florida Space Coast.
