A 'new star' has exploded into the night sky — and you can see it from North America
When you buy through links on our articles, Future and its syndication partners may earn a commission. A "new star" is shining in the constellation Lupus thanks to an unexpected stellar explosion within the Milky Way — and it can currently be seen with the naked eye from parts of North America. On June 12, astronomers from the All-Sky Automated Survey for Supernovae at Ohio State University first spotted the new point of light, which had an apparent magnitude of +8.7 at the time, still too dim to be seen by the naked eye, Sky & Telescope originally reported. (A smaller magnitude signifies a brighter object; for example, the moon has an apparent magnitude of -12.7). Over the next few days, the rapidly brightening object took on several temporary names — including AT 2025nlr, ASASSN-25cm, and N Lup 2025 — as researchers scrambled to determine its identity. Astronomer Yusuke Tampo, from the South African Astronomical Observatory at the University of Cape Town, then analyzed the light coming from the object and determined that it is likely a classical nova — a massive stellar explosion that temporarily shines bright in the night sky. On June 16, it was given the official designation V462 Lupi. By June 18, V462 Lupi had brightened to an apparent magnitude of +5.7, which makes it just visible to the naked eye. This also makes it around 4 million times brighter than its extremely dim progenitor star was before June 12, according to Related: Nearly 900 years ago, astronomers spotted a strange, bright light in the sky. We finally know what caused it. There is a chance that the nova will continue to brighten in the coming days, making it even easier to spot. The Lupus constellation is located in the southern sky, meaning that V462 Lupi is most easily visible from the Southern Hemisphere. However, it can also be seen from North America, close to the southern horizon, just after sunset. Amateur astronomers from the U.S. have reported seeing it in places such as Arizona and California, and as far north as Lake Superior, according to Sky & Telescope. You may be able to spot it without any additional equipment. However, it would be easier to spot if you had a decent telescope or a pair of stargazing binoculars, especially if you are viewing it from the U.S. or if the explosion starts to dim over the coming days. Unlike supernovas, which are so powerful that they completely rip stars apart, a nova only affects the outer layer of a star. Classical novas, such as V462 Lupi, occur in a specific type of binary system, where a more massive white dwarf star is pulling material away from its larger partner. When enough material has been accreted onto the dwarf star's surface, the pressure builds up and triggers an explosion that burns up most of the stolen gas and shoots pulses of bright light toward Earth. Naked-eye classical novas are rare. They appear "no more than once a year," representatives wrote, "and most are so close to the limit of naked-eye sensitivity that they can be invisible despite being technically [visible]." RELATED STORIES —Supernova that lit up Earth's skies 843 years ago has a flowering 'zombie star' at its heart — and it's still exploding —Mystery explosion 1,000 years ago may be a rare, third type of supernova —Rare quadruple supernova on our 'cosmic doorstep' will shine brighter than the moon when it blows up in 23 billion years Some novas are also recurring events, blowing their top at regular intervals: For example, the long-awaited T Coronae Borealis nova, also known as the "Blaze Star," lights up our skies roughly every 80 years. However, astronomers have been predicting that the Blaze Star will reappear imminently for the last 15 months, and it is yet to emerge, which shows that it is not an exact science. As this is the first recorded appearance of V462 Lupi, we have no idea if or when it will explode again in the future.

OSU professor to explain the evolution of medicine in Marion talk
A free community lecture on drug design will take place in Marion on July 8. Ohio State University Professor Ryan Yoder will present 'The Evolution of Drug Design: From Remedies to Rationality' at 5:30 p.m. at Bucci's Italian Scratch Kitchen. The event is part of the Buckeye Talks on Tap lecture series sponsored by The Ohio State University at Marion, according to an annoucement. Yoder's presentation will explore the history of drug design, detailing how medicines have evolved from ancient remedies to modern therapies. He will discuss the shift from chance discoveries to systematic, science-based approaches in drug development. The lecture also will cover how advancements in technology, research methods, and regulations have influenced the creation and testing of medicines. Yoder earned his Ph.D. in organic/computation chemistry from The Ohio State University in 2013. He teaches organic chemistry and mentors undergraduate research at the Ohio State Marion campus. His research focuses on drug design for cancer therapies, molecular modeling against toxic organophosphorus nerve agents, and innovative teaching methods in chemical education. Buckeye Talks on Tap occurs on the second Tuesday of each month at Bucci's Italian Scratch Kitchen, 320 W. Center St., Marion. The series is modeled after the Science Café concept, which promotes engaging discussions between academic experts and the community in relaxed settings.

Juneteenth is still a federal holiday, but not everyone deserves the day off
Juneteenth is still a federal holiday, but not everyone deserves the day off | Opinion Real freedom should be for us all. Juneteenth is a holiday for all Americans. And one day, all Americans will deserve the day off for it. Show Caption Hide Caption What is Juneteenth, America's newest federal holiday? Juneteenth marks the emancipation of enslaved Black Americans. It became a federal holiday in 2021. Juneteenth is described as America's second Independence Day or Freedom Day, commemorating the end of slavery in Texas. The holiday gained national prominence in 2020 following protests against racial injustice and was made a federal holiday in 2021. The author argues that some Americans, particularly those who oppose civil rights and diversity, don't deserve to celebrate Juneteenth. Millions of Americans will get Thursday, June 19, off work to observe Juneteenth. Millions of Americans don't deserve it. That's certainly the case for the lawmakers in Ohio and around the nation behind efforts to cripple civil rights, erase accurate, unvarnished history, and keep Americans afraid of Americans. That's certainly the case for the university presidents and business leaders in Ohio and around the nation who surrendered their morality to national forces bent on making America less diverse and more unjust and exclusionary. That's certainly the case for Americans in Ohio and around the nation who secretly or openly applaud as doors are slammed shut for those deserving of the same freedom they are afforded. Cowardly decisions like the one Ohio State University made to close two campus offices focused on diversity, equity and inclusion will have consequences for real people. So will Ohio University's work to root out scholarships earmarked for minorities, women and members of the LGBTQ+ community. There are sadly so many examples. Opinion: I remember my first Juneteenth. It's more than a Black holiday. Not everyone deserves to celebrate Juneteenth I wish it were not the case, but these folks don't deserve to celebrate the events of June 19, 1865. They should have to work on Juneteenth or, better yet, be required to gift their day off to a soul forced to work who believes in liberty and justice for all. These Americans don't get that Juneteenth – "June" and "nineteenth" – not only celebrates the Emancipation Proclamation but also the liberation of America. They don't get that slavery held all of America in bondage, and that clinging to superiority and inequality is a bear trap that injures us all. These Americans will get Juneteenth off, nevertheless. Juneteenth is a federal holiday but it's new to me. Is it important to you? Tell us. | Opinion Forum Why is Juneteenth celebrated? There will be picnics, festivals and other jubilant events for the holiday. Those fighting in the name of oppression shouldn't go. I can only hope they'll consider the meaning behind America's second Independence Day or Freedom Day, as it is called. More than two years after the Emancipation Proclamation was signed by President Abraham Lincoln, the Union Army and Gen. Gordon Granger arrived in Galveston, Texas and ordered enslaved Blacks be set free. Slavery's history in America: See how slavery grew in the U.S. over two centuries Juneteenth has been commemorated in Texas, the last of the Confederate states to have Lincoln's order announced, since June 19, 1866. The holiday gained prominence in 2020 after nationwide protests were sparked by the police killings of George Floyd, Breonna Taylor and other Black people and drew attention to ongoing racial inequalities. President Joe Biden made Juneteenth a federal holiday in 2021. Banks, the U.S. Postal Service, schools and government offices will be closed for Juneteenth. Real freedom should be for us all. Juneteenth is a holiday for all Americans. One day, all Americans will deserve the day off for it.

Boston student remains stuck in Israel as conflict with Iran escalates
As the Israel and Iran conflict escalates, Boston-Needham native Naomi Carr-Gloth is one of many foreign students stuck in Israel as the airspace remains closed. Boston-Needham native stuck in Israel "It was really scary when one missile hit a five-minute walk from me. It was this huge explosion, and it was terrifying. Probably the scariest thing I've ever gone through," Carr-Gloth said. She is in Tel Aviv as part of an internship program that has just been cancelled for safety concerns. "We're sort of stuck. The program is over, but our program is working hard to get us out of the country, back to the U.S., as soon as possible," Carr-Gloth said. She arrived in Israel in May as part of a 10-day birthright trip. She stayed with friends and family until her Ohio State University internship program started in June. Now that the internship is canceled, the program has moved all the students south of Tel Aviv to a safer area. Right now, she's not sure when she will be able to fly out. "Obviously, it's scary, but, you know, I have family and friends here who have been going through these things for years - especially since Oct 7th," she said. Travel advisory for Israel This week, the State Department raised its travel advisory for Israel to Level 4, the highest level, and warned U.S. citizens not to travel to the country. Eighteen-year-old Naomi Stoll just graduated from Gann Academy in Waltham and plans to do a gap year in Jerusalem to be part of a 10-month Torah study program to deepen her knowledge of Jewish text and to volunteer. Stoll just returned from Israel last month as part of her senior trip. If allowed, she plans to go back in August. "Of course, I am nervous because ballistic missiles are being, like, shot at the country which I am going to, but I can't live my life in fear. I'm hoping and praying for peace," she said. Both women said their love for Israel runs deep and they wouldn't change their experiences, no matter how unsettling things are right now.
