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 ...

The four most promising worlds for alien life in the solar system

The Earth's biosphere contains all the known ingredients necessary for life as we know it. Broadly speaking these are: liquid water, at least one source of energy, and an inventory of biologically useful elements and molecules.

Solar storm forecasts for Earth improved with help from the public

Solar storm analysis carried out by an army of citizen scientists has helped researchers devise a new and more accurate way of forecasting when Earth will be hit by harmful space weather.Scientists at the University of Reading ...

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 ...

Image: Mesh reflector for shaped radio beams

This prototype 2.6-m diameter metal-mesh antenna reflector represents a big step forward for the European space sector: versions can be manufactured to reproduce any surface pattern that antenna designers wish, something ...

Venus' ancient layered, folded rocks point to volcanic origin

An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic ...

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 ...

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 ...

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 ...

Five new giant radio galaxies discovered

With the help of citizen scientists, astronomers have detected five new giant radio galaxies (GRGs). The new GRGs have sizes ranging from 2.3 to 2.6 million light years, and have been identified at redshift between 0.28 and ...

How scientists around the world track the solar cycle

Every morning, astronomer Steve Padilla takes a short walk from his home to the base of a tower that soars 150 feet above the ground. Tucked in the San Gabriel Mountains, about an hour's drive north from Los Angeles, the ...
