3 generations of women from the same family are all heading to this Wisconsin college
Instead of calling your extended family to tell them how college is going, how about meeting up with them on campus after classes? These four women can do just that. Carthage College welcomed three generations of women on campus this fall semester, a grandmother, a mother, and her two daughters.

Scientists just detected a ‘cosmic bass note’ in the depths of space
Scientists just detected a ‘cosmic bass note’ in the depths of space
A low intergalactic grumbling is emanating from deep space, according to scientists. And no, it’s not the start of the end times. Astronomers say they detected the first-of-their-kind low frequency ripples, described as a “cosmic bass note” of gravitational waves, which is thought to be caused by supermassive black holes merging across the universe. The discovery could unveil new secrets about how the monster black holes, which lie at the centre of galaxies, work. The objects are millions – possibly billions – the times the mass of the sun, but little is known about them because no light can escape. Sign up to our free Indy100 weekly newsletter “This is huge news,” said Dr Stephen Taylor, chair of the North American Nanohertz Observatory for Gravitational Waves (Nanograv) consortium, which led the team which made the discovery, and an astrophysicist at Nashville’s Vanderbilt University. Dr Michael Keith, of Jodrell Bank Centre for Astrophysics and a member of the team which helped find the signal, added: “The results presented today mark the beginning of a new journey into the universe to unveil some of its unsolved mysteries. “We are incredibly excited that after decades of work by hundreds of astronomers and physicists around the world, we are finally seeing the signature of gravitational waves from the distant universe.” Before the discovery, scientists have only captured short “chirps” of gravitational waves which are linked to the massive objects merging. But the “bass note” comes after they tuned into a deeper range of frequencies. It is thought to be caused by a single complete gravitational wave travelling at the speed of light. Astronomers think it is produced by the entire population of supermassive black hole binaries from over roughly the last 8bn years of the universe. “We think each pair contributes a little wave, which is added to a little wave of another, and all together that is what we may see right now – a sort of murmur of the entire population,” said Prof Alberto Vecchio of the University of Birmingham and a member of the European Pulsar Timing Array. Prof Andrew Pontzen, a cosmologist at University College London, added: “It’s not often that we get a glimpse of the universe through a totally new lens, but after 15 years of patient work, Nanograv seems to be providing just that. It’s tremendously exciting to see initial evidence for these waves, which will eventually teach us an enormous amount about supermassive black holes, hundreds of millions of times the mass of the sun.” The findings were published on 29 June by Astrophysical Journal Letters.

Nasa spots shocking number of galaxies like our own in early universe
Nasa spots shocking number of galaxies like our own in early universe
Scientists have spotted a shocking number of galaxies like our own in the early universe. The finding will prompt us to entirely rethink our understanding of how the universe formed the structures that surround us. Looking deep into space, scientists found that the galaxies we see in the early universe are much more like our own Milky Way than was thought possible. A team of international researchers including those at The University of Manchester and University of Victoria in Canada, used the James Webb Space Telescope (JWST) to discover that galaxies like the Milky Way are 10 times more common than what was believed based on previous observations with the Hubble Space Telescope. Many of these galaxies formed some 10 billion years ago or longer, going far back into the history of the universe. The Milky Way is a typical disk galaxy, with a shape similar to a pancake or compact disc, rotating about its centre and often containing spiral arms. These galaxies might be the kind where life can develop given the nature of their formation history, experts suggest. Astronomers previously considered these types of galaxies too fragile to exist in the early universe when galaxy mergers were more common, destroying what was thought to be their delicate shapes. Christopher Conselice, professor of extragalactic astronomy at The University of Manchester, said: “Using the Hubble Space Telescope we thought that disc galaxies were almost non-existent until the universe was about six billion years old, these new JWST results push the time these Milky Way-like galaxies form to almost the beginning of the universe.” He added: “These JWST results show that disc galaxies like our own Milky Way, are the most common type of galaxy in the universe. “This implies that most stars exist and form within these galaxies which is changing our complete understanding of how galaxy formation occurs. “These results also suggest important questions about dark matter in the early universe which we know very little about.” “Based on our results, astronomers must rethink our understanding of the formation of the first galaxies and how galaxy evolution occurred over the past 10 billion years.” The researchers say their findings, published in the Astrophysical Journal, completely overturn the existing understanding of how scientists think the universe evolves, and the scientists say new ideas need to be considered. Lead author Leonardo Ferreira, from the University of Victoria, said: “For over 30 years it was thought that these disc galaxies were rare in the early universe due to the common violent encounters that galaxies undergo. “The fact that JWST finds so many is another sign of the power of this instrument and that the structures of galaxies form earlier in the universe, much earlier in fact, than anyone had anticipated.” The improved technology of JWST allows astronomers to see the true structure of these galaxies for the first time.
