A few years later, hints of a second planet arose, with a mass of about six Earths and a five-year orbit. Both of these planets orbit within the star's habitable zone, where temperatures are just right for liquid water to potentially gather on the surface. And now astronomers have detected signs of a third planet in the system. Proxima d, as it's known, is actually closer to the star than its siblings, orbiting every five days at a distance about one-tenth of Mercury's distance from the Sun. That makes it a bit too close to be in the habitable zone. Proxima d was discovered using the radial velocity technique, which involves watching for slight wobbles of a star produced by the gravitational pull of orbiting planets. In this case, that wobble was tiny, moving Proxima Centauri back and forth at about 1.44 km/h (0.89 mph), meaning it took follow-up observations to confirm it wasn't just the star itself changing. With a mass just one quarter that of Earth, Proxima d is now the lightest exoplanet ever discovered using this method. "This achievement is extremely important," said Pedro Figueira, an author of the study. "It shows that the radial velocity technique has the potential to unveil a population of light planets, like our own, that are expected to be the most abundant in our galaxy and that can potentially host life as we know it." As exciting as it is to find new planets so close, we might need to look further afield to find signs of life. Red dwarfs are known to be more active, throwing off flares and radiation that would strip away the atmospheres of orbiting exoplanets. Proxima Centauri itself has even shown that rowdy side, with a huge flare detected in 2017 far surpassing anything our Sun is capable of. Billions of years under this kind of space weather would likely sterilize any planet of its atmosphere and oceans long before life could take hold, even it were located within the habitable zone. Still, it's a fascinating star system, and its proximity to us makes it a worthwhile target for further study. The research was published in the journal Astronomy & Astrophysics.

"Sea levels continue to rise at a very alarming rate, and it's endangering communities around the world," Bill Nelson, administrator of the National Aeronautics and Space Administration (NASA), told reporters during an online briefing. "And that means it's past time to take action on this climate crisis." Man-made carbon emissions, however, cannot be totally blamed for the inevitable rise, according to Richard Spinrad, NOAA administrator. "Current and future emissions matter, but this will happen no matter what we do about emissions," Spinrad said. "If emissions continue at their current pace, it is likely we will see at least two feet (61 centimeters) of sea-level rise by the end of this century along the U.S. coastlines." With the forecast of an average sea level rise of 10-12 inches (25.4 cm to 30.5 cm) by 2050, about 140,000 homes would be at risk of being flooded about every other week, according to the report. Forty percent of the U.S. population lives within about 100 kilometers of a coastline. The sea level rise will intensify high tides, storm surges, coastal erosion and loss of wetlands. "Communities now dealing with nuisance flooding will be facing more damaging floods in just 30 years' time," said Nicole LeBoeuf, director of the NOAA National Ocean Service. "Another way to think about this is that a single flooding event, one that now happens every four to five years on average, in coastal communities in the southeast United States will occur four to five times per year." The projections in the document are based on observations from coastal tide gauges and satellite imagery. Nelson, a former U.S. senator, said the current administration is taking a whole-of-government approach to confront climate change. "Different agencies, finally, are coming together to leverage their expertise to advance our understanding and planning for the future," Nelson said. "This new data on sea rise is the latest reconfirmation that our climate crisis - as the president has said - is blinking 'code red,'" Gina McCarthy, the White House national climate adviser, said in a statement. "We must redouble our efforts to cut the greenhouse gases that cause climate change, while at the same time, help our coastal communities become more resilient in the face of rising seas." In response to a question from VOA about what the best mitigation projects for the federal government and communities would be to undertake, William Sweet, an oceanographer at NOAA's National Ocean Service, said it is all about being on higher ground. Storm water systems will need to be examined, he explained, and "when there's an opportunity to relocate major infrastructure - schools, fire departments, energy plants - elevation needs to be considered," said Sweet, the lead author of the 111-page report. Among the worst-hit U.S. cities by midcentury: Galveston in Texas and St. Petersburg in Florida, which are forecast to see about a 60 centimeter rise in the sea level over the next four decades. A study published in January in monthly journal Nature Climate Change predicted the cost of damage annually by flooding in the United States could increase 26% by the year 2050, totaling more than $40 billion, and it noted poor communities would be disproportionately affected. Early in the next century, there will be even worse trouble ahead, according to Sweet. That is when the melting ice sheets in Antarctica and Greenland are likely to send even more sea water onto distant shores. https://www.voanews.com/a/us-sea-levels-rising/6443051.html  tooooei gopti elCwhatn  This is Shortwave Radiogram in MFSK64 Please send your reception report to radiogram@verizon.net This week's images ...  # o tyäcnetR tn  Remembering Bob Bruninga, WB4APR, creator of the Automatic Packet Reporting System (APRS) and expert on alternative power sources. https://bit.ly/351lhVe ...  itTtnttic  Sending Pic:206x149C;  tno‹wq et  Our propagation indicator is this vertical red line. https://redlinefoundation.ch ...  tR vdL¨senf  Sending Pic:195x168C;  itex  This goby with a red anemone background in the Sea of Oman is a winner of the 2022 Underwater Photographer of the Year awards. https://bit.ly/356NHwU ...
