There’s a “runaway” black hole which has been speeding through the universe and mystifying the scientific community – or so we thought. Now, a possible explanation has been found that could explain the unusual, long star structures which have been observed over recent weeks. Last month, scientists thought they’d discovered something very unusual, with a trail of stars observed by the Hubble Space Telescope. Some believed then that they were the result of a black hole creating eye-catching formations. Yale University researchers also posited the theory that the formation after two galaxies merged together millions of years ago.

In one sense it is also a pity, because the existence of fleeing black holes is expected, and this could have been the first one to be observed.” The team published its findings in the journal Astronomy and Astrophysics under the title “Supermassive black hole wake or bulgeless edge-on galaxy?”. They compared the unusual feature to a galaxy IC5249 and found it to be similar. They found that it was surprisingly similar. The stars were moving in similar ways to those found in closer, comparative galaxies, researchers said. “We also looked at the relation between the mass of the assumed galaxy and its maximum velocity of rotation, and discovered that indeed it is a galaxy which behaves like a galaxy,” said Ignacio Trujillo, an IAC researcher who worked on the study. “It is an interesting object, because it is quite a large galaxy at a very large distance from Earth, where the majority of the galaxies are smaller.” Have your say in our news democracy.

Space is full of mysteries which we will never likely solve but, generally, we at least know a thing or two about craft we send out into the cosmos. Not so, when it comes to one probe which has just touched back down on Earth after 276 days in orbit. The experimental spacecraft was launched by China’s space agency, ostensibly to test the nation’s reusable space technologies. According to state media agency Xinhua News, the mission’s aim was to help with the development of “more convenient and affordable round-trip methods for the peaceful use of space in the future”. Sign up for our free Indy100 weekly newsletter That all sounds pretty similar to what SpaceX and NASA are up to, except that the Chinese spacecraft and its journey have been shrouded in secrecy. No information has been released on the altitude it reached or the systems it tested. We don’t even know where it went or, indeed, what kind of spacecraft it was – not a single image has been released to the public. Commentators on Chinese social media have speculated that Beijing has been developing a spacecraft like the UAir Force's X-37B, an autonomous spaceplane that can remain in orbit for years. However, no one knows how well this is going nor, indeed, if it’s going at all. All we do know about China’s latest unidentified flying object is that it was launched from the Jiquan Satellite Launch Center in the Gobi Desert on August 5, 2022 and returned to the same site on 8 May, 2023. It follows an earlier mission, carried out in July last year, which saw a Chinese spacecraft fly to the edge of the Earth’s atmosphere and back on the same day. The country’s main space contractor, China Aerospace Science and Technology Corp (CASC), hailed the success of the craft’s brief celestial jaunt at the time. It gushed: "The development of reusable space transportation technology is an important symbol of China's transition from a 'big' space-faring nation to a 'powerful' space-faring one.” Have your say in our news democracy.

The Eurovision song contest takes place this weekend in Liverpool after Ukraine won last year. Kalush Orchestra came out on top in 2022 with a huge show of support for their song 'Stefania' - and have since handed over hosting duties to the UK because of the ongoing war with Russia. Speaking of the UK, Mae Muller has been selected to represent the country and will perform her song 'I Wrote A Song' at the final. Sign up to our free Indy100 weekly newsletter With glory and hosting duties to play for, then, choosing a good song is very important. So who (or what) better to turn to than ChatGPT, everyone's favourite controversial AI system, to write a song for us? That is exactly what we did and here's what the software came up with: Verse 1: Under the bright lights, We stand here tonight, In this moment we unite, With hearts open wide. Chorus: We dance to the beat of our own drum, We sing with passion until the night is done, We are the stars that light up the sky, We are the ones who never say die. Verse 2: We come from every corner, From the north to the south, We share the same desire, To let our voices out. Chorus: We dance to the beat of our own drum, We sing with passion until the night is done, We are the stars that light up the sky, We are the ones who never say die. Bridge: Let's forget about the past, Let's live in the moment that will last, Together we'll make history, And show the world what we can be. Chorus: We dance to the beat of our own drum, We sing with passion until the night is done, We are the stars that light up the sky, We are the ones who never say die. Outro: So let's keep dancing, And keep singing our song, We'll show the world who we are, And prove that we belong. So there you have it - ChatGPT could become the next best singer. After all, we reckon this song is probably better than half the actual entries we will endure this weekend. Have your say in our news democracy.

A plan by Elon Musk to delete inactive Twitter accounts has sparked a huge backlash - including from Andrew Tate. Musk has announced he will delete accounts that have not been used in a while, warning people that this will see them lose followers. But while that isn't the end of the world, some have expressed concern that the accounts of deceased family members will go too - cutting people off from seeing a history of their loved one's 140-character thoughts. Sign up to our free Indy100 weekly newsletter Controversial commentator Tate, who is now under house arrest following months of detainment in a Romanian prison on suspicion of human trafficking, rape, and organised criminal activity, had an issue with the plan for instance. He tweeted: And others weighed in with their views: According to Twitter's policy, users should log in to their accounts at least once every 30 days to avoid permanent removal due to prolonged inactivity. But there is a way to save tweets. To export an archive, go to your account settings by clicking the "more" icon in the navigation bar and selecting your account from the menu. Then click on download an archive of your data. Nevertheless, it seems that Twitter's new regime is continuing to give people a headache. Have your say in our news democracy.
