Searching for Phosphorus in Other Stars

Searching for Phosphorus in Other Stars The Search for Life can be a lot messier than it sounds. The three words make a nice, tidy title, but what it entails is extraordinarily difficult. How, in this vast galaxy, can we find life and the planets or moons that might host it? We’re barely at the […]

VLBA makes first direct distance measurement to magnetar

VLBA makes first direct distance measurement to magnetar Astronomers using the National Science Foundation’s Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy—a measurement that could help determine if magnetars are the sources of the long-mysterious Fast Radio Bursts (FRBs). phys.org […]

How planetary nebulae get their shapes

How planetary nebulae get their shapes About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most of that helium into carbon and oxygen. It will have swollen to a size large enough to fill the solar system nearly to the current […]

Weekly Space Hangout: September 16, 2020 – Dr. Merav Opher Discusses the Shape of the Sun’s Heliosphere

Weekly Space Hangout: September 16, 2020 – Dr. Merav Opher Discusses the Shape of the Sun’s Heliosphere This week we are pleased to welcome Dr. Merav Opher, Professor from the Astronomy Department of Boston University and the Director of the SHIELD (Solar wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) DRIVE Science Center. Using […]

Hubble captures crisp new portrait of Jupiter’s storms

Hubble captures crisp new portrait of Jupiter’s storms This latest image of Jupiter, taken by NASA’s Hubble Space Telescope on Aug. 25, 2020, was captured when the planet was 406 million miles from Earth. Hubble’s sharp view is giving researchers an updated weather report on the monster planet’s turbulent atmosphere, including a remarkable new storm […]

Astronomers capture stellar winds in unprecedented detail

Astronomers capture stellar winds in unprecedented detail Astronomers have presented an explanation for the shapes of planetary nebulae. The discovery is based on a set of observations of stellar winds around aging stars. Contrary to common consensus, the team found that stellar winds are not spherical, but have a shape similar to that of planetary […]

Climate change impacts astronomical observations

Climate change impacts astronomical observations Climate changes associated with global warming can affect astronomical observations. That is the result of a study involving scientists from the University of Cologne. The international research team investigated a range of climate parameters at the Very Large Telescope (VLT) at the Paranal in the Atacama Desert in Chile, where […]

Sunrises Across the Solar System

Sunrises Across the Solar System Scientists have learned a lot about the atmospheres on various worlds in our Solar System simply from planetary sunrises or sunsets. Sunlight streaming through the haze of an atmosphere can be separated into its component colors to create spectra, just as prisms do with sunlight. From the spectra, astronomers can […]

Research reveals an enormous planet quickly orbiting a tiny, dying star

Research reveals an enormous planet quickly orbiting a tiny, dying star Thanks to a bevy of telescopes in space and on Earth—and even a pair of amateur astronomers in Arizona—a University of Wisconsin-Madison astronomer and his colleagues have discovered a Jupiter-sized planet orbiting at breakneck speed around a distant white dwarf star. The system, about […]

Solar cycle 25 has begun

Solar cycle 25 has begun In the past one and a half years, the sun has been rather dull: hardly a sunspot covered its surface, hardly a solar flare hurled radiation and particles into space. As observational data now show, for the last nine months solar activity has been slowly picking up again. Already in […]

Scientist searches for stellar phosphorus to find potentially habitable exoplanets

Scientist searches for stellar phosphorus to find potentially habitable exoplanets A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes […]
