machine learnings implimentation in education will be staggeringly productive.

observing the student it will know precisely whats not getting through and which of the many ways to address it are best likely to susceed given their profile. truely amazing productivity.

back to rockets.



SpaceX on Thursday test fired 31 of the 33 engines in the towering rocket booster of its Starship prototype, as the company prepares to launch the rocket to orbit for the first time. CNBC reports:

Called a "static fire," the milestone test is the final major hurdle before SpaceX tries to launch the nearly 400-foot-tall rocket to space. The company said in a tweet shortly after the test that the engines at the base of the Super Heavy booster fired for "full duration," meaning the expected length of the test. CEO Elon Musk said in a subsequent tweet that SpaceX turned off one engine before the test and another engine "stopped itself." "Still enough engines to reach orbhttps://www.cnbc.com/2023/02/09/spacex-test-fir ... ter.htmlit!" Musk said.

SpaceX has steadily been building up to the first flight test of its Starship rocket. President and COO Gwynne Shotwell on Wednesday stressed the first launch attempt would be experimental. The company will next analyze the result of Thursday's static fire test. Shotwell estimated that a successful static would see SpaceX ready to launch the first Starship orbital flight "within the next month or so."

a fucking piece of the sun broke off...

just in case you were to lazy to click.


The Sun has always fascinated astronomers. And now, a new development has baffled scientists. A huge part of the Sun broke off of its surface and created a tornado-like swirl around its North Pole. Though scientists are trying to analyse how this occurred, the video of the development has stunned the space community. The remarkable phenomenon was caught by NASA's James Webb telescope and shared on Twitter by Dr Tamitha Skov, a space weather forecaster, last week. The Sun keeps emitting solar flares (called prominence) that sometimes affect communications on Earth, hence scientists are more concerned about the latest development.

"Talk about Polar Vortex! Material from a northern prominence just broke away from the main filament & is now circulating in a massive polar vortex around the north pole of our Star. Implications for understanding the Sun's atmospheric dynamics above 55 degrees here cannot be overstated!" Dr Skov said in a tweet last week.
According to NASA, the prominence is a large bright feature extending outward from the Sun's surface. There have been several such instances in the past but this one has stumped the scientific community.

"More observations of the #SolarPolarVortex reveal it took roughly 8 hours for material to circumnavigate the pole at approximately 60 degree latitude. This means an upper bound in the estimation of horizontal wind speed in this event is 96 kilometers per second or 60 miles a second!" Dr Skov said in a subsequent tweet.

Solar physicist Scott McIntosh of the US National Centre for Atmospheric Research, who has been observing the Sun for decades, told Space.com that he had never seen a "vortex" like the one that occurred when a piece of the prominence broke away and was whipped into the solar atmosphere.

Space scientists are now analyzing the strange event to gather more details about it and present a clearer picture. Though our favourite star is monitored round-the-clock, it keeps throwing surprises, like the multiple powerful flares this month that disrupted communication on Earth.

A candidate runaway supermassive black hole identified by shocks and star formation in its wake

The interaction of a runaway supermassive black hole (SMBH) with the circumgalactic medium (CGM) can lead to the formation of a wake of shocked gas and young stars behind it. Here we report the serendipitous discovery of an extremely narrow linear feature in HST/ACS images that may be an example of such a wake. The feature extends 62 kpc from the nucleus of a compact star-forming galaxy at z=0.964. Keck LRIS spectra show that the [OIII]/Hβ ratio varies from ~1 to ~10 along the feature, indicating a mixture of star formation and fast shocks. The feature terminates in a bright [OIII] knot with a luminosity of 1.9x1041 ergs/s. The stellar continuum colors vary along the feature, and are well-fit by a simple model that has a monotonically increasing age with distance from the tip. The line ratios, colors, and the overall morphology are consistent with an ejected SMBH moving through the CGM at high speed while triggering star formation. The best-fit time since ejection is ~39 Myr and the implied velocity is v~1600 km/s. The feature is not perfectly straight in the HST images, and we show that the amplitude of the observed spatial variations is consistent with the runaway SMBH interpretation. Opposite the primary wake is a fainter and shorter feature, marginally detected in [OIII] and the rest-frame far-ultraviolet. This feature may be shocked gas behind a binary SMBH that was ejected at the same time as the SMBH that produced the primary wake.
