In space, no one can hear you scream — but they may be able to hear a black hole.
NASA’s Exoplanets Twitter account unveiled audio where listeners can hear what a black hole from 200 million light-years away sounds like to the human ear.
The space agency also used the tweet to address the widely misunderstood notion that there is no sound among the stars.
“The misconception that there is no sound in space originates because most space is a vacuum, providing no way for sound waves to travel,” they wrote.
“A galaxy cluster has so much gas that we’ve picked up actual sound. Here it’s amplified, and mixed with other data, to hear a black hole!” they excitedly tweeted alongside a video clip of said hole moaning and groaning. The account is run by a team of scientists investigating exoplanets, or planetary orbs found outside of our solar system.
The cluster featured in the video is called Perseus, and the finding was initially released in May in honor of NASA’s Black Hole Week. The data was discovered by NASA’s Chandra X-ray Observatory.

The daughter of Alexander Dugin, known to be Russian President Vladimir Putin’s closest aide, was allegedly killed in a car bomb explosion, according to several media reports. The explosion that killed Darya Dugin is alleged to have been targeted at her father – famously called Vladimir Putin’s ‘Rasputin’ and ‘Putin’s brain’.
Alexander Dugin, 60, is said to have been the mastermind behind the Russian invasion of Ukraine. His daughter, an occult writer, has been widely known for her far-right ideology and is popularly regarded as her father’s ‘guru advisor’. Daria Dugina was included in UK sanctions lists in July this year.

While transactions made through Unified Payment Interface or UPI are free of cost at present, the Reserve Bank of India has now sought feedback from stakeholders on the possibility of imposing a tiered charge on them. The RBI on Wednesday, August 17, released a discussion paper on charges in payment systems to structure its policies and streamline the framework of charges for different payment services/ activities in India.
.
These include UPI, IMPS (Immediate Payment Service), NEFT (National Electronic Funds Transfer), RTGS (Real-Time Gross Settlement) and payment instruments including debit cards, credit cards, and prepaid payment instruments (PPIs). “Based on the feedback received, RBI would endeavour to structure its policies and streamline the framework of charges for different payment services / activities in the country. At this stage, it is reiterated that the RBI has neither taken any view nor has any specific opinion on the issues raised in this discussion paper,” said the RBI in the discussion paper.
.
On whether the charges should be levied on UPI payments, the RBI chalked out some points. “UPI as a funds transfer system is like IMPS. Therefore, it could be argued that the charges in UPI need to be similar to charges in IMPS for fund transfer transactions. A tiered charge could be imposed based on the different amount bands," said the central bank. The RBI sought responses and suggestions from stakeholders by October 3 this year.
