The measurements of the expansion of the universe don’t add up

The measurements of the expansion of the universe don’t add up Physicists use two types of measurements to calculate the expansion rate of the universe, but their results do not coincide, which may make it necessary to update the cosmological model. “It’s like trying to thread a cosmic needle,” explains researcher Licia Verde of the […]

Zeroing in on baby exoplanets could reveal how they form

Zeroing in on baby exoplanets could reveal how they form Twenty-four years ago, Swiss astronomers Michel Mayor and Didier Queloz discovered the first planet orbiting a sun-like star outside our solar system—a milestone recognised by this year’s Nobel prize in physics. Today we know of thousands more ‘exoplanets,” and researchers are now trying to understand […]

Two of Neptune’s Moons Dance Around Each Other as they Orbit

Two of Neptune’s Moons Dance Around Each Other as they Orbit Like a long-married couple accustomed to each other’s kitchen habits, two of Neptune’s moons are masters at sharing space without colliding. And though both situations may appear odd to an observer, there’s a certain dance-like quality to them both. We’re talking about Thalassa and […]

Nearly extreme black holes which attempt to regrow hair become bald again

Nearly extreme black holes which attempt to regrow hair become bald again Black holes ‘have no hair’: no attributes that can be used to tell them apart. Extreme black holes (spinning at maximally allowed rate) can have an additional property, permanent hair that is made of a massless scalar field. Nearly extreme black holes (like […]

Image: Hubble spots a curious spiral The universe is simply so vast that it can be difficult to maintain a sense of scale. Many galaxies we see through telescopes such as the NASA/ESA Hubble Space Telescope, the source of this beautiful image, look relatively similar: spiraling arms, a glowing center, and a mixture of bright […]

Making planets in a rocket

Making planets in a rocket How are celestial bodies created? Aside from philosophical questions, researchers are taking practical steps to investigate the very first moments when planets are born—on a sounding rocket launching from Sweden next week. phys.org Go to Source

It’s Time for Hayabusa-2 to Come Home

It’s Time for Hayabusa-2 to Come Home Japan’s Hayabusa 2 spacecraft is on its way home. The asteroid-visiting, sample-return mission departed asteroid Ryugu (162173 Ryugu) on Wednesday, beginning its year-long journey back to Earth. And it’s carrying some precious cargo. Hayabusa 2 launched in December 2014, and arrived at Ryugu near the end of June, […]

Apollo 12 Launched 50 Years Ago Today

Apollo 12 Launched 50 Years Ago Today The 50th anniversary of Apollo 11 was a huge celebration, and Apollo 13 may be an equally big commotion. Apollo 12 is tough sell in the middle. Even the Virginia Air & Space Center, which houses the Apollo 12 capsule, uses photographs of Apollo 11 to advertise. Ouch.  […]
