New Super-Crisp Images of Neptune Show How Far Our Telescopes Have Come

Posted by in category: space

This is a new picture of Neptune taken from the Earth. It’s nothing short of amazing.

You’ve probably seen better pictures of Neptune from when Voyager 2 flew by in 1989. But there isn’t currently a spacecraft orbiting Neptune, so if scientists want pictures, they need to take them from 2.9 billion miles away. An upgrade on the Very Large Telescope at the European Southern Observatory in Chile has now allowed the ground-based telescope to take images as crisp as those taken by Hubble, a telescope that orbits Earth.

The Very Large Telescope consists of four telescopes with 8.2-meter (27-foot) mirrors in northern Chile’s Atacama Desert. Today, scientists at the observatory have released the first observations taken with laser tomography, the new adaptive optics mode on its GALACSI unit, which works alongside a spectrograph instrument called MUSE on one of the telescopes.

On this day: 15 July 1799

Posted by in category: space

On this day: 15 July 1799, as French soldiers were strengthening the defences of Fort Julien, just north-east of the Egyptian port of Rosetta (Rashid), Lt Pierre-François Bouchard spotted a slab of stone with inscriptions on one side that his soldiers had uncovered. This slab was named the Rosetta Stone, and a few hundred years later, the name would be carried by ESA’s Rosetta Mission, hoping to unlock the secrets of a comet… More at http://www.britishmuseum.org/research/collection_online/coll…1&partId=1

NASA director reverses on climate change, after 1 month

Posted by in categories: astronomy, climatology, education, environmental, ethics, existential risks, governance, government, lifeboat, science, space, sustainability

For millennia, our planet has sustained a robust ecosystem; healing each deforestation, algae bloom, pollution or imbalance caused by natural events. Before the arrival of an industrialized, destructive and dominant global species, it could pretty much deal with anything short of a major meteor impact. In the big picture, even these cataclysmic events haven’t destroyed the environment—they just changed the course of evolution and rearranged the alpha animal.

But with industrialization, the race for personal wealth, nations fighting nations, and modern comforts, we have recognized that our planet is not invincible. This is why Lifeboat Foundation exists. We are all about recognizing the limits to growth and protecting our fragile environment.

Check out this April news article on the US president’s forthcoming appointment of Jim Bridenstine, a vocal climate denier, as head of NASA. NASA is one of the biggest agencies on earth. Despite a lack of training or experience—without literacy in science, technology or astrophysics—he was handed an enormous responsibility, a staff of 17,000 and a budget of $19 billion.

In 2013, Bridenstine criticized former president Obama for wasting taxpayer money on climate research, and claimed that global temperatures stopped rising 15 years ago.

Can We Measure Our Own Galaxy Speeding Through Space?

Posted by in categories: physics, space, transportation

You’re probably sitting still, right? Wrong, absolutely wrong. Not only are you on a spinning orb, but you’re also traveling around 70,000 miles per hour around a star, in a galaxy that, observations imply, is sailing through space at over a million miles per hour.

If the above numbers seem shocking, they shouldn’t be. The laws of physics look and feel the same for any object so long as it’s not accelerating, the way you can’t feel that a car is traveling at a steady 60 miles per hour unless you look out the window. But that also makes our galactic speed hard to measure from here on Earth. The million-plus mile per hour number is based on measurements of how the most distant objects in the Universe appear to move in comparison to us, but scientists want to try to measure our acceleration by looking at more nearby objects.
