Earlier today, Apple announced that its new generation of phones, iPhone 14 and iPhone 14 Pro, will have the Emergency SOS feature. It will allow sending distress messages and sharing location by connecting directly to satellites. So, how exactly will it work?

One of the biggest questions facing astronomers today concerns star formation and its role in the evolution of galaxies. In particular, astronomers are curious whether the process began in the central regions of galaxies, where stars are more tightly bound. Previous observations have shown that numerous galaxies experienced intense periods of star formation in their centers roughly one billion years after the Big Bang. For some time, astronomers have wanted to conduct similar observations of the Milky Way’s Galactic Center to study rapid star formation more closely.
Unfortunately, it has been very difficult for astronomers to study the center of the Milky Way because of how bright and densely packed the region is, which makes it difficult to discern individual stars and clusters. Thanks to a new analysis of a high-resolution infrared survey, a team of astronomers has created the first reconstruction of the star formation history in the Galactic Center. According to their findings, most young stars in this region formed in loose stellar associations that dispersed outwards to fill the Galactic Disk over the course of many eons (as opposed to tightly-knit massive clusters).

Here’s the Tarantula Nebula like we’ve never seen it before. The James Webb Space Telescope turned its detectors towards the Large Magellanic Cloud about 161,000 lightyears away to take a look at 30 Doradus, more commonly known as the Tarantula Nebula. JWST’s exceptional infrared view has now revealed thousands of never-before-seen young stars in this stellar nursery, as well incredible views of the wispy, dusty filaments and the impressive collection of massive older stars.
There is so much detail in this image, if you download the full-sized version, you can pan and zoom around to see details on stars and the surrounding dust and gas. And there are even other, more distant galaxies dotting the background. If you have a big screen, even better, as it takes up over 14,000 x 8,000 pixels. Or, take a look at the video tour, below.

Asteroids are commonly thought of as solid balls of rock and metal – a place where Bruce Willis can land and stick a nuke into the middle of it. But as we learn more about them, it is becoming more evident that many asteroids are just piles of rubble held loosely together by gravity. So it might not be too big of a surprise when some of those pieces of rubble fly off of the asteroid itself. But it surprised scientists who first observed the phenomena on the asteroid Bennu when OSIRIS-REx visited it in 2019. Now a team led by researchers at the field museum found a meteorite that shows signs it underwent the same process.

In a joint effort between NASA’s MAVEN spacecraft and the United Arab Emirates’ Emirates Mars mission (EMM), scientists have observed an uncommonly chaotic interaction between the solar wind and Mars’ upper atmosphere, creating a unique ultraviolet aurora. The phenomenon represents an unusual occurrence in Martian space weather, and scientists are excited to take advantage of future collaborations between spacecraft to keep an eye out for repeat events.

In 1982, author James Michener published his sprawling Space Race novel, Space. In it, he describes a fictional Apollo 18 mission to the Moon. While the astronauts are on the surface, the Sun unleashes a huge storm, trapping them outside of their protective capsule. The two men get blasted by lethal amounts of radiation before they can get to safety.

Rice is one of the world’s staple crops. It is regularly eaten by more than half the world’s population. And now, it’s been grown in microgravity, on board the newly launched Chinese Wentian space laboratory.
Wentian launched in July and joined up with the Tianhe module of China’s new space station. Its original complement of eight experiments included one that attempted to grow rice in microgravity.

Green sand might sound like a strange thing to find on the Red Planet, but that is exactly what a new paper from researchers led by a team at Purdue found in images from Perseverance.

Private spaceflight is taking off, though some are going faster than others. As SpaceX preps for its sixth crewed launch on a NASA contract, their rival Boeing has announced that they will be delaying the first crewed flight of their Starliner spacecraft until February 2023.

Reusable rocket engines have become all the rage lately, even as NASA’s continually delayed Artemis I mission attempts to launch with non-reusable technology. Realistically the only way to significantly lower launch costs is to reuse the engines rather than build them from scratch every time. Which is why every fan of space exploration should rejoice that another small start-up company, RocketLab, has successfully retested a rocket that has flown in space.
