April 19, 2017: The hits, they just keep coming!

News was made in February when astronomers found seven potential earth-like planets orbiting the red dwarf star Trappist-1.

Wednesday, another red dwarf star is making headlines with the announcement of a ‘super earth’ found orbiting around the small red star LHS 1140.

VOA spoke with Jason Dittmann, from the Harvard-Smithsonian Center for Astrophysics, about the find.

He is the lead author of the paper laying out the new findings, which is being published Thursday in the journal Nature.

He calls the planet a “Super Earth,” not because it’s any better than our blue-green sphere, but because it “is somewhere between the size of the Earth (the largest rocky planet in the Solar System) and Neptune. These planets are actually pretty common, but we don’t have any of them in our own Solar System so we don’t know much about them.”

Finding one is a big deal in general. But this one, dubbed LHS 1140b, is extra-special because it has turned up in the dwarf star’s habitable zone, that area in space where liquid water can exist on the surface.

The planet is 10 times closer to the star than Earth is to the sun, but red dwarfs are much smaller and much cooler than the giant inferno that keeps us warm.

The other special thing about this planet is that it’s about 5 billion years old, and according to Dittmann, “Five billion years should be more than enough time for life to develop [if it’s easy to develop, no one knows!] So this is definitely a good thing.”

Too close for comfort

In general, one big problem with the habitable planets scientists have found around red dwarfs — and this goes for a few of the seven they’ve found on Trappist-1 — and Proxima b, another found last year — is that they are so close to their star that the stellar radiation that is bombarding the planets can literally strip away any atmosphere.

NewsGram brings to you top news around the world today.

And this may be the case here.

But LHS 1140, according to team member Nicola Astudillo-Defru, “spins more slowly and emits less high-energy radiation than other similar low-mass stars.” That’s good news because the planet is so old and so big that chances are decent that it’s managed to hold onto an atmosphere.

Another bit of good news is that terrestrial planet LHS 1140b as seen from earth passes almost directly in front of its star, and that makes it a lot easier to do follow up research that Dittmann and his colleagues are already planning.
“We’re definitely already applying for as much telescope time as we can get our hands on,” Dittmann says, “to start looking at this planet’s atmosphere. And when the next generation of telescopes come online [The James Webb Space Telescope, and the ground-based Giant Magellan Telescope (GMT) and European-Extremely Large Telescope (EELT) ], we’ll be in a great spot to find out what sorts of atmospheres planets around M dwarfs have.”

The Webb telescope is expected to launch next year, but the Giant Magellan telescope won’t be online until 2025, and the EELT won’t be working until 2024.

That’s a long time to wait, and undoubtedly there’ll be a long list of planets to explore by then. But the hope is that by studying the atmosphere of all these planets in the habitable zone, we might find some of the biological signatures of living things. Two of the European members of the team, Xavier Delfosse and Xavier Bonfils say that it’s the best candidate so far.

“The LHS 1140 system might prove to be an even more important target for the future characterization of planets in the habitable zone than Proxima b or TRAPPIST-1. This has been a remarkable year for exoplanet discoveries!” wrote Delfosse and Bonfils.

And there certainly will be more on the way. (VOA)

What is the Future of US-India Relations? Here’s the Answer

The US presidential elections and future of India-US relations

Given the love fests of Prime Minister Narendra Modi's 'Howdy Modi' event in Houston, Texas, in which Trump participated in September of 2019, and Trump's 'Namaste Trump' event hosted by Modi in India in February of this year, it might be assumed that the future for US-India relations is a splendid one.

BY FRANK F. ISLAM

As the coronavirus pandemic dominates global news in the United States, progress toward the next presidential election scheduled to be held on November 3 moves slowly forward. President Donald Trump had no real opposition in the Republican party and is running for re-election. And it has now become apparent that former Vice President Joe Biden will be his opponent as the Democratic candidate for president.

What would a Trump victory bode for the future of US-India relations? What would a Biden victory bode? Let me answer each of those questions in turn.

Given the love fests of Prime Minister Narendra Modi’s ‘Howdy Modi’ event in Houston, Texas, in which Trump participated in September of 2019, and Trump’s ‘Namaste Trump’ event hosted by Modi in India in February of this year, it might be assumed that the future for US-India relations is a splendid one. This would be an incorrect assumption.

Both of these events were more symbolic than substantive. Trump’s participation in them undoubtedly helped to persuade some — perhaps many — Indian American Modi supporters who voted for Hillary Clinton in 2016 to cast their ballots for Trump in 2020. Trump’s campaign team took steps to ensure this by holding an event at his Mar-a-Lago resort in which a group of prominent Indian Americans announced their plans to work for his re-election and to mobilize Indian Americans on his behalf.

To understand the future potential of India’s relations with the US. with Trump as president, however, it is necessary to look beyond these political moves and to examine the present state of those relations and Trump’s personal style.

In a word, the best way to characterize the current relations between the US and India is “functional”. The relationship was relatively good for the first two years of Trump’s presidency. In fact, near the end of 2018, Alice Wells, the Acting Assistant Secretary of State for South and Central Asia, was quoted in the media s saying: “This has been a landmark year for US-India ties as we build out stronger relationships across the board.”

Then, in 2019, the relations went off the track in the first half of the year after the US and India got into a tit-for-tat tariff war after the US terminated India’s Generalized System of Preferences which allowed India to send certain goods to the US duty-free. There have been continuing efforts to structure a “modest” trade deal since then. It was thought there might be some type of deal done in September of 2019 while Modi was in the US by year’s end, and then during Trump’s India visit. But, as of today, there is still no deal.

This inability to get any meaningful trade agreement in place speaks volumes about India’s potential future relations with India with Trump as president. So, too does Trump’s style.

Trump’s campaign slogans this time around are “Keep America Great” and “Promises Made, Promises Kept.” Trump is not a policy wonk and most of his effort will go toward “America First”. This involves making the US more isolated by withdrawing from international agreements, restructuring trade agreements, emphasizing building walls to stop immigrants at the border, using tariffs to block trade with countries who are taking away American jobs, and confronting businesses who are allegedlly stealing American trade secrets.

This perspective suggests what India can expect for its relations with the US if it has to deal with Trump for a second term as president. The relations will stay functional at best. As I have said before, that’s because the words partnership, cooperation and collaboration are not in Trump’s vocabulary. Nationalism, isolationism and protectionism are.

Joe Biden stands in stark contrast to President Trump both professionally and personally. Biden is a strategic thinker and doer with a solid eight-year track record of leadership experience as Vice-President in forging alliances that have made a difference around the world and he has also been a long-standing friend of India.

He was chairman of the Senate Foreign Relations Committee and a leading advocate for the Congressional passage of the Indo-US civic nuclear deal in 2005. At a dinner convened 10 years later in 2015 by the Confederation of Indian Industry and the Carnegie Endowment for International Peace, Vice President Biden discussed the tremendous joint progress that had been made by the two countries in the past and declared “We are on the cusp of a sea change decade.”

Early in his campaign for the Democratic nomination for president in July of 2019, in laying out his foreign policy vision, Biden stated that the US had to reach out to India and other Asian partners to strengthen ties with them. The items on Biden’s foreign policy agenda for strengthening which are of importance for India include climate change, nuclear proliferation and cyberwarfare.

During his vice presidency, Biden worked side by side with President Barack Obama to do things that would contribute to achieving Obama’s vision stated in 2010 of India and America being “indispensable partners in meeting the challenges of our time.” In 2020, those challenges are even greater than they were a decade ago.

That is why it is so essential that India and the US develop a strategic relationship that enables them to become those indispensable partners. That can happen if Biden assumes the presidency on January 20, 2021. It cannot happen if Donald Trump remains as president for a second term.

Find out How Coronavirus Pandemic Has Disrupted Global Food Supplies

Explainer: How Coronavirus Crisis Is Affecting Food Supply

The coronavirus pandemic has disrupted global food supplies and is causing labor shortages in agriculture worldwide. This is the latest health news.

Are there food shortages?

Panic buying by shoppers cleared supermarket shelves of staples such as pasta and flour as populations worldwide prepared for lockdowns.

Meat and dairy producers as well as fruit and vegetable farmers struggled to shift supplies from restaurants to grocery stores, creating the perception of shortages for consumers.

Retailers and authorities say there are no underlying shortages and supplies of most products have been or will be replenished. Bakery and pasta firms in Europe and North America have increased production.

Food firms say panic purchasing is subsiding as households have stocked up and are adjusting to lockdown routines.

The logistics to get food from the field to the plate, however, are being increasingly affected and point to longer-term problems.

In the short term, lack of air freight and trucker shortages are disrupting deliveries of fresh food.

In the long term, lack of labor is affecting planting and harvesting and could cause shortages and rising prices for staple crops in a throwback to the food crises that shook developing nations a decade ago.

What’s disrupting the food supply?

With many planes grounded and shipping containers hard to find after the initial coronavirus crisis in China, shipments of vegetables from Africa to Europe or fruit from South America to the United States are being disrupted.

A labor shortage could also cause crops to rot in the fields.

As spring starts in Europe, farms are rushing to find enough workers to pick strawberries and asparagus, after border closures prevented the usual flow of foreign laborers. France has called on its own citizens to help offset an estimated shortfall of 200,000 workers.

More wide-scale crop losses are looming in India, where a lockdown has sent masses of workers home, leaving farms and markets short of hands as staple crops like wheat near harvest.

Is food going to cost more?

Wheat futures surged in March to two-month highs, partly because of the spike in demand for bakery and pasta goods, while corn (maize) sank to a 3½-year low as its extensive use in biofuel exposed it to an oil price collapse.

Benchmark Thai white rice prices have already hit their highest level in eight years.

Swings in commodity markets are not necessarily passed on in prices of grocery goods, as food firms typically buy raw materials in advance. A sustained rise in prices will, however, eventually be passed on to consumers.

Some poorer countries subsidize food to keep prices stable.

The U.N. Food and Agriculture Organization has warned that a rush to buy by countries that rely on imports of staple foods could fuel global food inflation, despite ample reserves of staple crops.

Fresh produce such as fruit or fish or unprocessed grains such as rice reflect more immediately changes in supply and demand.

Will there be enough food if the crisis lasts?

Analysts say global supplies of the most widely consumed food crops are adequate. Wheat production is projected to be at record levels in the year ahead.

However, the concentration of exportable supply of some food commodities in a small number of countries and export restrictions by big suppliers concerned about having enough supply at home can make world supply more fragile than headline figures suggest.

Another source of tension in global food supply could be China. There are signs the country is scooping up foreign agricultural supplies as it emerges from its coronavirus shutdown and rebuilds its massive pork industry after a devastating pig disease epidemic. (VOA)
