How is it going, how did it start?

A comparison of AR3053 and AR3052 between July 10 and July 5 when they rotated into view on the Eastern limb of the Sun. The active regions on both dates captured in Ca II K, H alpha and white light. 
AR3053 (centre) and AR3052 (small spot on RHS of image) in Ca II K light (363.3nm) on July 10.

AR3053 (left near E solar limb) and AR3052 (small spot(s) nearer centre of image) in Ca II K light (363.3nm) on July 5. AR3051 is just visible in top RH corner of the image.

The change in 3053 is majestic while 3052 has dissipated over the course of the five days. looking forward to a few more cloud free days to follow groups across the solar disk on a daily basis!

One of the most established scholarly disciplines of science, Physical science created as exceptional exploration exercises in its own ability. Groundbreaking thoughts during the physical science meetings will make sense of the central systems concentrated on by different sciences and propose new roads of examination in different related scholarly disciplines.
Material science International Conference is crucial to the economy as it add to the monetary result as well as utilize in excess of 1,000,000 individuals. Physical science and its connected area will engage the worldwide market beginning from agro-tech to wind power age. From energy age to imaginative meds, material science and physical science based organizations assume an imperative part in spurring curiosity and development of new skill .All Upcoming Academic Physics Conferences Worldwide
Gatherings Worldwide is a worldwide forerunner in creating great meetings, gatherings, studios and culminations in all significant areas of science, innovation and medication. Since its commencement, Gatherings Global has been related with public and global affiliations, organizations and undeniable level people, devoted to have a-list meetings and occasions.
Physical science meetings can make a nearby connection between fundamental science and mechanical applications which will be useful to the advancement in exploration and development. Gatherings Global through year around gatherings, culminations, gatherings center around building long haul associations with speakers, delegates and supporters to guarantee that our projects are proper as well as interface with this present reality difficulties and amazing open doors looked by our clients.
Our speakers and agents address the main trend-setters in their particular fields, with a hunger for information and an eagerness to share both their prosperity and disappointments. Our speakers and representatives address the main trend-setters in their particular fields, with a hunger for information and a readiness to share both their prosperity and disappointments.
We invite every one of the energetic specialists to go during our time around physical science meetings list and be a piece of the excursion.

“New images of the sun's chromosphere—the lower region of the solar atmosphere—have been released, and to say they are "stellar" is an understatement. Simply, they are stunning. The high-resolution images were taken with the now-fully-operational Daniel K. Inouye Solar Telescope, located on the summit of Haleakala, Maui, in Hawai'i. Scientists say the new observatory—with its large 4-meter (13-ft) primary mirror—will enable a new era of solar science, and provide a leap forward in understanding the sun and its impacts on our planet.”

““With the world's largest solar telescope now in science operations, we are grateful for all who make this remarkable facility possible," said Matt Mountain, President of the Association of Universities for Research in Astronomy (AURA) "In particular we thank the people of Hawai'i for the privilege of operating from this remarkable site, to the National Science Foundation and the U.S. Congress for their consistent support, and to our Inouye Solar Telescope Team, many of whom have tirelessly devoted over a decade to this transformational project. A new era of Solar Physics is beginning."
One of the primary goals of the Inouye Solar Telescope is to gain a better understanding of the solar dynamics. This in turn will also help scientists predict and prepare for solar storms, called coronal mass ejections (CME). CMEs send hot plasma from the sun's corona, and if Earth is in the path, this can damage satellites in Earth orbit and interfere with power grids on the planet. Scientists hope to be able to improve their predictions of major weather events. Presently, space agencies are able to anticipate events about 48 minutes ahead of time. But with the new telescope, they are hoping to make predictions 48 hours in advance.”

The Unusual Auroras of Mars
Tumblr media
Earth, Saturn, and Jupiter have auroras at their poles, generated by the interaction of their global magnetic fields with the solar wind. Mars has no global magnetic field, only remnants of one frozen into areas of its crust; yet it, too, has auroras.  (Image credit: R. Lillis et al.; research credit: C. Bowers et al. and B. Johnston et al.; via APS Physics) Read the full article

Sentences, that sparkled like the stars.”

The far reaches of the Solar System are a dim and distant realm with particulars that elude us. So far from the light of the Sun, even a relatively large planet could easily escape our notice. The trans-Neptunian objects (TNOs) that we have found out there, beyond the orbit of Neptune, exhibit some peculiar clustering behaviors that could indicate the presence of a hidden world. This has led scientists to propose the idea of Planet Nine, a large terrestrial planet lurking far beyond the range of visibility. Now, two scientists have come up with an alternative explanation: a more modest, Earth-like world, located much closer than the disputed Planet Nine, on a tilted orbit that could explain the curious behaviors attributed to the presence of something larger. According to planetary scientists Patryk Sofia Lykawka of Kindai University in Japan and Takashi Ito of the National Astronomical Observatory of Japan, this world, frozen and dark so far from the Sun, would be no greater than 3 times the mass of Earth, and no farther than 500 astronomical units from the Sun.

"I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up. Many people feel small, because they’re small and the Universe is big. But I feel big, because my atoms came from those stars."
- Neil deGrasse Tyson

Sun's not all fire! 🌞 It's got a 4-layer atmosphere of scorching plasma. Corona's the hottest, millions of degrees! Read through to know more about these layers.

This is Ethan Peck visiting JPL to take a look at the Europa Clipper, a spacecraft that will be launched in October towards the Jovian moon in hopes of exploring that strange new world!
Just look at how happy and nerdy he looks at JPL. Props to whoever invited him, because it's only logical to invite Mr. Spock to JPL. And props to Ethan for supporting science and exploration! I love this man 🖖🥹

yk I love that the eclipse trio poly is becoming more of a thing bc frankly I've been making Solar and Eclipse hate kiss for a WHILE now, but now with Ruin they can both have a little cringefail boyfriend that makes them not want to beat the shit out of each other gay style (temporarily)
