If Biden were to pass away due to old age before November and Harris took over as President, would that benefit or hurt her campaign in any way?

The title sums it up: If Biden were to pass away due to old age before November and Harris assumed the presidency, would this benefit or harm her chances in the 2025 presidential campaign?

In other words, would stepping into the role of president provide a boost to her campaign or serve as a setback? Read More...

Bright lights detected by NASA telescopes lead to a dancing pair of supermassive black holes

Two telescopes have spotted the closest pair of supermassive black holes to date. The duo, only about 300 light-years apart, were observed in different wavelengths of light using NASA’s Chandra X-ray Observatory and the Hubble Space Telescope.

While black holes are invisible against the dark void of space, these two blaze brightly as the gas and dust they feed on is accelerated and heated to high temperatures. Both celestial objects, which circle around one another, are known as active galactic nuclei.

Active galactic nuclei are supermassive black holes that release bright jets of material and high winds that can shape the very galaxies where they are found.

The black hole duo is the closest pair found through visible and X-ray light. While other black hole pairs have been observed before, they are usually much farther apart. Astronomers discovered these black holes dancing around one another at the center of a pair of colliding galaxies called MCG-03-34-64, which is 800 million light-years away.

Astronomers serendipitously found the black holes when Hubble’s observations revealed three spikes of bright light within the glowing gas of a galaxy. They published their discovery Monday in The Astrophysical Journal.

“We were not expecting to see something like this,” said lead study author Anna Trindade Falcão, a postdoctoral researcher at the Center for Astrophysics | Harvard & Smithsonian in Cambridge, Massachusetts, in a statement. “This view is not a common occurrence in the nearby universe, and told us there’s something else going on inside the galaxy.”

Zooming in on bright cosmic lights
The team was intrigued when Hubble picked up on three optical diffraction spikes in a concentrated region of the MCG-03-34-64 galaxy. Diffraction spikes appear when light from a small cosmic region bends around the mirror inside telescopes.

Hubble’s observations were made in optical light, which is visible to the human eye, but the astronomers weren’t sure what they were seeing. Falcão’s team took another look at the galactic region with Chandra in X-ray light.

When the scientists observed the galaxy using Chandra, they were able to pinpoint two powerful sources of X-ray light that matched the optical light sources spotted by Hubble, Falcão said. “We put these pieces together and concluded that we were likely looking at two closely spaced supermassive black holes.”

The team also consulted archival observation radio wave data collected by the Karl G. Jansky Very Large Array of radio telescopes near Socorro, New Mexico. The black hole duo was also found to release energetic radio waves.

“When you see bright light in optical, X-rays, and radio wavelengths, a lot of things can be ruled out, leaving the conclusion these can only be explained as close black holes. When you put all the pieces together it gives you the picture of the (active galactic nuclei) duo,” Falcão said.

Meanwhile, the third diffraction spike observed by Hubble has an unknown origin, and the team requires more data to understand what it could be. The source of light might be from gas that was shocked by an energetic release of material from one of the black holes.

“We wouldn’t be able to see all of these intricacies without Hubble’s amazing resolution,” Falcão said.

Astronomers have observed pairs of black holes that are closer together than these two through radio telescopes, but those duos haven’t been observed in other wavelengths of light.


Both supermassive black holes once served as the centers of their respective galaxies, but a galactic merger brought the two objects much closer together. Eventually, their close spiral will result in a merger in about 100 million years, according to NASA, causing an energetic release of gravitational waves, or ripples in the fabric of space and time.

Such gravitational waves created by the collisions of supermassive black holes could be detected in the future by LISA, the European Space Agency-led Laser Interferometer Space Antenna mission that’s expected to launch in the mid-2030s.

Patients turned away as doctors hold mass strike in India over rape and murder of trainee medic

Sexual violence against women is a widespread problem in India - many crimes are believed to go unreported due to stigma and a lack of faith in police.

Patients are being turned away from hospitals and clinics across India as more than a million doctors are set to join a strike in protest at the rape and murder of a trainee medic.

The 24-hour strike began at 6am local time (1.30am UK time) with non-emergency treatment such as outpatient appointments and elective procedures cancelled, said the Indian Medical Association (IMA).

The mass walkout paralysed hospitals as staff from medical colleges were drafted in to help with emergency cases.

The strike was triggered by the killing of a 31-year-old trainee doctor, whose body was found on 9 August at the college where she worked in Kolkata.

A police volunteer was arrested but the victim's family believe it was a gang rape and that more people were involved.

The case has drawn comparisons with the notorious rape and murder of a student on a bus in New Delhi in 2012.

People demonstrated near parliament in the capital on Friday - as well as cities including Kolkata, Hyderabad and Mumbai - calling for tougher sentences and guarantees of safety for doctors.

The facility where the doctor was killed, the state-run RG Kar Medical College and Hospital, was attacked on Wednesday.

"Doctors, especially women are vulnerable to violence because of the nature of the profession," said the IMA in a statement on X.

"It is for the authorities to provide for the safety of doctors inside hospitals and campuses."

Sexual violence against women and girls is a widespread problem in India with 31,516 reports of rape in 2022 - a 20% increase on 2021, according to the National Crime Records Bureau.

Many are believed to go unreported due to a stigma over sexual assault and a lack of faith in the police.

The medical college case is being handled by India's central bureau of investigation after state government officers were accused of mishandling the case. Read More...
