New report details what happened to the Arecibo Observatory

In 1963, the Arecibo Observatory became operational on the island of Puerto Rico. Measuring 305 meters (~1000 ft) in diameter, Arecibo's spherical reflector dish was the largest radio telescope in the world at the time—a ...

World's first wooden satellite launched into space

The world's first wooden satellite has blasted off on a SpaceX rocket, its Japanese developers said Tuesday, part of a resupply mission to the International Space Station.

How many additional exoplanets are in known systems?

One thing we've learned in recent decades is that exoplanets are surprisingly common. So far, we've confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets were discovered using the ...

Another way to extract energy from black holes?

The gravitational field of a rotating black hole is powerful and strange. It is so powerful that it warps space and time back upon itself, and it is so strange that even simple concepts such as motion and rotation are turned ...

Scientists have figured out why Martian soil is so crusty

On November 26, 2018, NASA's Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) mission landed on Mars. This was a major milestone in Mars exploration since it was the first time a research ...

Moon waves goodbye to Hera

As ESA's Hera mission for planetary defense departed its homeworld, it looked back to Earth to show the moon orbiting around it. In this sequence of images the terrestrial disk gradually shrinks as the spacecraft recedes ...

Learning more about supernovae through stardust

Most of the diverse elements in the universe come from supernovae. We are, quite literally, made of the dust of those long-dead stars and other astrophysical processes. But the details of how it all comes about are something ...

Black hole study challenges Kerr solution assumptions

Black holes continue to captivate scientists: they are purely gravitational objects, remarkably simple, yet capable of hiding mysteries that challenge our understanding of natural laws. Most observations thus far have focused ...

Hubble and Webb probe surprisingly smooth disk around Vega

In the 1997 movie "Contact," adapted from Carl Sagan's 1985 novel, the lead character scientist Ellie Arroway (played by actor Jodi Foster) takes a space-alien-built wormhole ride to the star Vega. She emerges inside a snowstorm ...
