James' World 2

A new simulation of millions of galaxies has shown just how powerful the forthcoming Nancy Grace Roman Space Telescope (Roman) will be when it opens its eye to the universe. 

NASA says that the telescope will turn back the “cosmic clock” and allow astronomers to see space in a way they never have before. This should help scientists understand how the universe evolved from a sea of densely packed particles into the cosmos we see today full of stars and galaxies.

Set to launch no sooner than May 2027, Roman’s power to revolutionize astronomy lies in the fact that it will have the ability to capture vast regions of space in a single image. As a startling example of this boosted observing power, the simulation demonstrates how in just 63 days Roman can image an amount of sky that it would take the Hubble Space Telescope 85 years to capture. 

The real benefit of the Nancy Grace Roman Space Telescope will be felt when it is teamed up with its fellow space telescopes, with Hubble able to see a broader spectrum of light and the James Webb Space Telescope (JWST) offering deeper observations.”The Hubble and James Webb Space Telescopes are optimized for studying astronomical objects in-depth and up close, so they’re like looking at the universe through pinholes,” leader of a study describing the simulation and postdoctoral fellow at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, Aaron Yung, said in a NASA statement (opens in new tab). “To solve cosmic mysteries on the biggest scales, we need a space telescope that can provide a far larger view. That’s exactly what Roman is designed to do.”

Like a mighty bulldozer that has thrown a track, the Donald Trump campaign for president has lost its forward momentum, causing analysts and Trump foes to speculate on what will happen if the Manhattan mogul fails to drag himself over the 1,237-delegate hump required to win the Republican Party’s nomination on a first ballot.

If Trump stalls, the Republican convention could enter brokered mode. (See this Boston Globe piece for the specifics, especially this piece on the intricacies of Rule 40.) Ohio Gov. John Kasich is almost banking on a convention that would free delegates pledged to candidates—by virtue of primary or caucus victories—to cast their subsequent ballots for a candidate of their choosing, namely Kasich. At this point, the struggling Marco Rubio is lullabying himself to sleep with the vision of a brokered convention, and Ted Cruz is probably humming the tune, too.

The free-for-all of a brokered convention would unleash the greatest display of political back-stabbing and double-dealing since the 1924 Democratic National Convention, which took a record 103 ballots and 16 sweaty days to select a nominee. For the journalists amassed in Cleveland for the Republican convention, it would be like covering a small war, a tsunami, and a mass shooting simultaneously, and nearly as dangerous.

The parallels between the Democrats’ 1924 convention and the Republicans’ upcoming one are there for a columnist’s taking. The 1924 Democratic Party was as divided as the Republican Party is today, maybe more so. The convention is often called the “Klanbake” because one of the front-runners, white shoe lawyer, and former Wilson Cabinet member William G. McAdoo, was supported by the Ku Klux Klan. The Klan was a major source of power within the party, and McAdoo did not repudiate its endorsement. The other front-runner, New York Governor Al Smith, a Catholic who represented the party’s anti-Klan, anti-Prohibition wing (McAdoo also backed Prohibition, which was then the law of the land), and his faction failed by a slim margin to pass a platform plank condemning the Klan. The convention, which was held in Madison Square Garden, had no black delegates.

The Lyrid meteor shower, a bright and fast meteor shower, is expected to peak this weekend. The Lyrids have lit up the sky for the past 2,700 years and potentially dozens of meteors could be seen per hour.

The shower comes each April and the best time to watch this year will be between April 21 to 23. The peak is expected at 1:06 UTC on April 23 — or 9:06 p.m. EDT Saturday, April 22 — according to EarthSky. 

This year, there won’t be a full moon, and with the sky dark enough, stargazers may be able to see 10 to 15 Lyrids per hour. Sometimes they have surges that produce up to 100 per hour. 

Those who want to see the meteor shower won’t see long trails streaking through the sky. Instead, Lyrids may look like fireballs, according to NASA.

The best time to view the Lyrids is in the Northern Hemisphere after moonset but before sunrise in an dark area without streetlights, NASA advises. Lying flat on the ground to view as much of the sky as possible will give you the best chance to see the shower, which should last until dawn. 

The shower is named after where they originate from: the Lyra constellation. This is the shower’s radiant point, and NASA says you shouldn’t look directly at this part of the sky to see the best view of the Lyrids. Instead, they will appear longer if you look away from the radiant point.

Species are disappearing faster than ever before—and it’s because of humans. We’re destroying habitats and disrupting fragile ecosystems in a new wave of mass extinction that threatens Earth’s incredible biodiversity. That loss is sometimes overlooked in environmental discussions, as the focus rests on climate change. But our lives depend on the extraordinary variety of natural life around us.

To help slow this trend, turn to one of these 10 organizations below. They are just a few of the many working to protect the plants and animals that make up our world—from the colorful corals to the dense forests, from the largest whales to the smallest beetles. Donate to them, advocate with them, and learn from them.

Find even more environmental action inspiration in our How to Help the Planet collection, with advice on coexisting with creatures, making your wardrobe more sustainable, and more.

The three-bedroom, two-bath, split-level house in Fayetteville, Arkansas, looks like a perfect family home. It’s got a charming brick exterior, a lush, green front lawn, and a fenced-in backyard perfect for hosting cookouts. It’s on a quiet street with two schools and a Boys and Girls Club nearby. But this perfect family home has an unusual owner—or owners.

The property, which these days is known as the Soapstone, is “owned,” in a roundabout way, by 102 investors who have collectively purchased just over $100,000 in shares through a company called Arrived Homes. The property is managed and rented out for $1,600 a month, a bit below the city’s average rent of $1,795. Investors, who can buy in for as little as $100, get a cut of the profits.

And it’s not just the Soapstone. Arrived, alongside a handful of other so-called fractional investment startups, are adding yet more noise to an already-crowded real estate market. Investors can buy into hundreds of similar properties on the company’s website, where each listing has an Airbnb-style profile that breaks down the neighborhood, costs, number of bedrooms and bathrooms—and return on investment. 

In addition to Arrived, there’s Lofty AI, which uses a token model for people to buy in and lets them collect rent later that same day. Another company, reAlpha, sells shares in homes that serve as Airbnbs—including a treehouse resort in the works. Landa lets people invest in shares valued as low as $5 in houses around Atlanta or $20 in Brooklyn apartment buildings. Daniella Lang, a product marketer at the firm, says investors “see this as an American dream opportunity” that lets them build wealth in real estate. Anyone can click a button to invest—but that doesn’t really make them homeowners.

Part of the joy of travelling comes from experiencing the unfamiliar – a different climate, culture or cuisine. But when it comes to paying for things abroad, we might feel more comfortable using the currency we are most familiar with, the one we use at home.

This has recently become a common – and expensive – option for tourists withdrawing money from cash machines, or paying electronically in shops and restaurants.

When a restaurant bill arrives for example, foreign customers may be offered the choice on the card reader to pay in their home currency rather than the local one. This feature, known as “dynamic currency conversion” or “currency choice” sounds appealing at first – a service which has done the hard work for you, converting the bill to a currency you understand, giving you a better idea of how much money you are spending.

But it comes at a price – as the fees charged for this convenience can be exorbitant. In fact, one study shows that the average fee applied to this kind of conversion is a whopping 7.6%, more than double the cost of paying in the local currency (usually between 1.5% and 3%).

So suppose a French traveller goes out for dinner in a British town, and the final bill comes to £88.43, the equivalent of €100. Paying in UK currency, which would then converted to euros by the French diner’s bank, would lead to a payment of around €102. But using the dynamic currency conversion to pay the restaurant bill directly in euros would end up costing them €107.60.
