Observe spring’s star clusters

As winter’s brilliant stars slip toward the western horizon and the constellations of spring climb higher, Northern Hemisphere observers discover a quieter but richly rewarding sky. Spring is celebrated for its galaxies, yet our own Milky Way offers an equally compelling bounty of open and globular clusters. From youthful, loosely packed groups that still sparkleContinue reading “Observe spring’s star clusters” The post Observe spring’s star clusters appeared first on Astronomy Magazine.

SpaceX launches 29 Starlink satellites from Florida just hours after Blue Origin rocket explosion (video)

SpaceX launched 29 Starlink satellites from Cape Canaveral Space Force Station on Friday (May 29), about 12 hours after Blue Origin’s New Glenn rocket exploded on a different pad at the site.

Rocket Report: A dark day for Blue Origin; Pentagon eyes new launch site

Welcome to Edition 8.43 of the Rocket Report! A disclaimer: No one yet fully appreciates the ramifications of Blue Origin’s New Glenn rocket explosion Thursday night on its launch pad at Cape Canaveral, Florida. What we know as of this writing is that much of Blue’s sole orbital-class launch pad has been destroyed, and the New Glenn rocket will be grounded for an extended period of time. It is too soon for any hot takes, at least until the Sun rises at the Cape on Friday morning. One thing I am sure of is that we will be writing about Continue ReadingRocket Report: A dark day for Blue Origin; Pentagon eyes new launch site

ESA Selects Two New Scout-Class Missions

When it comes to understanding Earth and our changing environment, space is the place. Not only does it give us an overall holistic view of the planet below, but satellite-based imagery can transcend national boundaries and give us an understanding of key changes that often go unseen at ground level. Now, the European Space Agency (ESA) has chosen two new missions to address key questions in Earth environmental science: Hibidis and SOVA-S.

‘Shoot for the moon?’ Aim a bit lower, researchers say

How ambitious should you be? Folk wisdom offers conflicting advice: “Shoot for the moon,” but also, “Don’t let the perfect be the enemy of the good.” A new study by researchers at the University of Wyoming, Stanford University and the University of Colorado-Boulder used a mathematical model to show that ambition lies in the middle—above average but finite.

May 29, 1919: History’s most important eclipse

One of the most important eclipses in history happened in 1919. This particular eclipse cut a path across South America and the Atlantic Ocean, and landed on the west coast of Africa. Waiting on the island of Principe, in the Gulf of Guinea off the west coast of Africa, was a team of astronomers armedContinue reading “May 29, 1919: History’s most important eclipse” The post May 29, 1919: History’s most important eclipse appeared first on Continue ReadingMay 29, 1919: History’s most important eclipse

The Flash Memory That Space Can’t Destroy

Every byte of data a spacecraft collects, every image, every reading, every scientific measurement has to survive one of the most hostile environments imaginable. Space is awash with radiation, and that radiation is the silent enemy of conventional data storage. Now, a team of researchers have built a new kind of memory chip that doesn’t just tolerate radiation, it laughs in its face. Using a quirk of physics called ferroelectricity, this technology can withstand radiation levels equivalent to 100 million X-rays, and it could transform how we store data on missions heading deeper into the Solar System than we’ve ever ventured before.

20,000 Eyes on the Universe

We live in a golden age of astronomical imaging. Telescopes are capturing billions of galaxy images, painting the universe in breathtaking detail. But there’s a problem, and it’s a big one. A photograph tells you what something looks like but it doesn’t tell you what it’s made of, how fast it’s moving, or how far away it really is. For that, you need spectroscopy. And right now, astronomy has a catastrophic imbalance, billions of images and nowhere near enough spectra to match them. A new telescope currently under construction in the mountains of western China is about to change that quite dramatically.

We Can Now Weigh Galaxies Using Dead Stars As Scales

Researchers at the University of Alabama in Huntsville have found a new way to measure the mass of neighbouring galaxies using pulsars. Using the universe’s most precise natural clocks it’s possible to detect tiny gravitational disturbances rippling through the Milky Way. By analysing 54 millisecond pulsars, the team directly measured the gravitational pull of both the Large Magellanic Cloud and the Sagittarius Dwarf Galaxy, including their dark matter. The same technique could eventually map dark matter across the entire Galaxy bringing us closer to understanding what it actually is.

A tribute to Punch

Katelyn Beecroft from London, Ontario, Canada The Monkey Head Nebula (NGC 2174) lies roughly 5,000 light-years away in Orion. The nebula surrounds the young open cluster NGC 2175, and its star-forming dust clouds and wind-blown cavities suggests the outline of a simian face. The image comprises 6¾ hours of data taken in the Hubble paletteContinue reading “A tribute to Punch” The post A tribute to Punch appeared first on Astronomy Magazine.

Blue Origin’s New Glenn rocket explodes during prelaunch testing at Cape Canaveral

Blue Origin’s New Glenn rocket exploded on the pad at Launch Complex 36 at Cape Canaveral Space Force Station as the result of an anomaly during a static fire test on Thursday, May 28. The test was in preparation for a planned launch as soon as June 4.
