Nothing personal, the Sun is just going through a phase right now. On Jan 4, 2023, our planet reached the closest point to the Sun in its orbit and is expected to be hit by the wake of a coronal mass ejection (CME) coming from the Sun, Live Science reported.

Solar activity has been picking up pace in the past few months as the Sun approaches the peak of its solar cycle. Every 11 years or so, the poles on the Sun switch their positions, sending our star into a tizzy of activity, marked by the appearance of sunspots and darker areas on the solar surface.

Nothing personal, the Sun is just going through a phase right now.

On Jan 4, 2023, our planet reached the closest point to the Sun in its orbit and is expected to be hit by the wake of a coronal mass ejection (CME) coming from the Sun, Live Science.

A coronal mass ejection is a large expulsion of plasma and magnetic field from the solar surface. When the particles in this expulsion and the magnetic field interact with the Earth’s atmosphere and magnetic field, it compresses the latter, which is referred to as a geomagnetic storm.

Nearly a year after Sony and Honda shared plans to jointly make and sell electric vehicles, the two companies revealed a prototype under the brand name Afeela.

The four-door sedan was driven onstage at CES Wednesday as Kenichiro Yoshida, the CEO of Sony, talked through the company’s mobility philosophy, which prioritizes building vehicles that have autonomous capabilities and are transformed into “moving entertainment space[s].”

The first preorders of the Afeelas are scheduled in the first half of 2025, with sales to begin the same year, said Yoshida. Initial shipments will be delivered to customers in North America in the spring of 2026.

It’s all part of an in-space manufacturing initiative that could drastically reduce costs for future space missions.

A new experiment does away with one of the biggest hindrances manufacturers face here on Earth — Gravity.

MIT scientists are collaborating with NASA to build test parts in space as part of a research program aimed at unleashing the full potential of microgravity manufacturing.

Just like the distant galaxies, the deep seas continue to bring us wonder and awe.

Beyond every shoreline lies a sea, a seemingly uniform body of water with turbulent, ceaseless movement that joins the coastlines into a continuous whole, showing no sign of the borders and labels we set upon it. In many ways, these large bodies of water are as mysterious to us as the distant galaxies and stars in the cosmos. But they are also right here, in the midst of our own world and interacting with our planet’s atmosphere as a realm of hidden objects, shadowy dreams, and deep sea creatures.

Do you ever think about the creatures that lie deep below the seas?

Wait, how many stars were at this party? It’s likely there were up to five – but only two appear now! A research team recently began digging into Webb’s highly detailed images of the Southern Ring Nebula to reconstruct the scene. It’s possible more than one star interacted with the dimmer of the two central stars, which appears red in this image, before it created this jaw-dropping planetary nebula. The first star that “danced” with the party’s host created a light show, sending out jets of material in opposite directions. Before retiring, it gave the dim star a cloak of dust. Now much smaller, the same dancer might have merged with the dying star – or is now hidden in its glare.

A third partygoer may have gotten close to the central star multiple times. That star stirred up the jets ejected by the first companion, which helped create the wavy shapes we see today at the edges of the gas and dust. Not to be left out, a fourth star with an orbit projected to be much wider, also contributed to the celebration. It circled the scene, further stirring up the gas and dust, and generating the enormous system of rings seen outside the nebula. The fifth star is the best known – it’s the bright white-blue star visible in the images that continues to orbit predictably and calmly.

The final showstopping finding is an accurate measurement of the mass that the central star had before it ejected its layers of gas and dust. Researchers estimate the star was about three times the mass of the Sun before it created this planetary nebula – and about 60 percent of the mass of the Sun after. It’s still early days – this is some of the first published research about some of Webb’s first images to be released, so plenty more details are sure to come.
