New Hubble Space Telescope readings show the last moments of a star before it’s devoured by a black hole.
Astronomers used NASA’s iconic Hubble Space Telescope to record detailed observations of a star’s final moments before it was torn apart by a black hole.
As per a NASA blog post, the astronomers used Hubble to focus on the immense gravitational impact on the dying star.

The team recreated a turbulent magnetic reconnection, suggested to be a trigger of solar flares.
On January 10, NASA’s Solar Dynamics Observatory recorded a massive X-class solar flare. The blast hurled debris into space, and radiation from the flare triggered radio blackouts across the South Pacific. The solar outburst was the third X-class — the most powerful — flare in less than a week.
These intense bursts of radiation from the release of magnetic energy associated with sunspots can be dangerous — in February 2022, SpaceX lost 40 of its newly launched Starlink communications satellites due to a geomagnetic storm triggered by a solar flare.
The study has shown that the use of intense lasers can be used to divert lightning, much like conventional “Franklin rods.”
According to a report published in Nature Photonics.
The research could improve lightning protection strategies for vital infrastructure like power plants, airports, and launch pads.
The decline has come faster than the governments predicted. Will this change China’s stance?
Population in China has dipped for the first time in over 60 years, as per data released by the National Bureau of Statistics today. The country that had 1.41260 billion people in 2021 now has 1.41175 billion at the end of 2022. The small difference in decimals here is actually a difference of 850,000 people on the ground.
The decline in China’s population comes in the backdrop of the country reeling under an intense wave of COVID-19 infections after letting go of its ‘zero-COVID’ policy.

Tel-Aviv-based AI21 Labs launched today Wordtune Spices, a writer-augmentation tool based on generative AI. Selecting from 12 different cues, writers can generate a range of textual options to add to and enhance sentences. Spices can also suggest statistics to strengthen an argument or sharpen a detail.
AI21 says Spices is not intended to replace writers but to function as a writing assistant, suggesting additional complete sentences that improve and enhance the text that is being written. It could help refine and enrich the main message of the text, bolster and enrich arguments, and add creative expressions such as a joke or inspirational quote.
AI21 is addressing the limitations of Large Language Models (LLM) by combining deep learning with old-fashioned AI.

SpaceX signed a new agreement with the U.S. National Science Foundation (NSF) to prevent Starlink satellites from interfering with astronomy.
SpaceX has long been criticized by astronomers for the brightness of its Starlink satellites. Elon Musk, the CEO of SpaceX, said in 2019 that SpaceX would ensure that Starlink has no material effect on discoveries in astronomy. “We care a great deal about science,” he said in a tweet.
Exactly, potentially helping billions of economically disadvantaged people is the greater good. That said, we’ll make sure Starlink has no material effect on discoveries in astronomy. We care a great deal about science.

Researchers using NASA
Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.” NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

(THE CONVERSATION) As with weeds in a garden, it is a challenge to fully get rid of cancer cells in the body once they arise. They have a relentless need to continuously expand, even when they are significantly cut back by therapy or surgery.
