We heart the Earth and sky

This Valentine’s Day, we find so much to love in the many heart-shaped objects created by Mother Nature that can be found right here on Earth or all the way to the deepest reaches of the sky. Source: https://earthsky.org/space/heart-shaped-objects-in-nature-space-earth-valentines-day…

NASA Spacecraft Discovers the Universe is Less Crowded Than We Thought

An anonymous reader shares a report: While we might think of space as a vast sea of blackness, all we have to do is look up at night to see that it’s punctuated by countless stars, galaxies and even a few planets visible to the naked eye. Scientists recently used data from NASA’s New Horizons mission out beyond Pluto to measure…

New Horizons spacecraft answers the question: How dark is space?

How dark is the sky, and what does that tell us about the number of galaxies in the visible universe? Astronomers can estimate the total number of galaxies by counting everything visible in a Hubble deep field and then multiplying them by the total area of the sky. But other galaxies are too faint and distant to directly detect. Yet while…

How will the U.S. space program fare under Joe Biden?

Joe Biden is the United States presidential election winner, but his plans for NASA remain unclear. And while citizens digest the election results, the space industry is left wondering what comes next. Source: https://earthsky.org/human-world/how-will-the-u-s-space-program-fare-under-joe-biden…

A surprising find of fast-moving gas from a young star

Pluto’s landscape more like Earth’s than previously thought

Voyager Spacecraft Detect An Increase In the Density of Space Outside the Solar System

As Voyager 2 moves farther and farther from the Sun, the density of space is increasing. “It’s not the first time this density increase has been detected,” notes SciencAlert. “Voyager 1, which entered interstellar space in 2012, detected a similar density gradient at a separate location.” From the report: Voyager 2’s new data show that not only was Voyager 1’s detection…

Pluto’s snowcapped mountains are unlike any on Earth

A new study shows how methane snow accumulates on Pluto’s mountain peaks. These snowcaps – first seen by New Horizons in 2015 – look a lot like ones on Earth, but form in a very alien environment. Source: https://earthsky.org/space/methane-snowcapped-mountains-on-pluto-new-horizons…

The mountains of Pluto are snowcapped, but not for the same reasons as on Earth

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed elsewhere in the Solar System. However, as atmospheric temperatures on our planet decrease at altitude, on Pluto they heat up at altitude as a result of solar radiation.
