This weekend the night sky will showcase a blue micromoon – a rare alignment of a second full moon in a calendar month and a moon at its most distant point from Earth.Understanding the Dual Phenomenon: Blue Moon Meets MicromoonA "monthly blue moon" occurs when a second full moon appears in the same calendar month, as explained by Dr Greg Brown of the Royal Observatory Greenwich. A micromoon happens when the full moon coincides with the moon’s apogee, making it appear roughly 6% smaller than a typical full moon and about 14% smaller than a supermoon.Numbers Behind the Rarity: Frequency and Size DifferencesBlue moons: roughly every 2‑3 years.Micromoons: 2‑3 times per year.Combined blue micromoon: about once every 20‑30 years.Size reduction: ~6% smaller than average full moon, ~14% smaller than a supermoon.Why Stargazers Should Take Note: Visibility and Cultural ContextThe full moon peaks on 31 May at 9.45am BST (4.45am ET, 6.45pm AEST). For observers in the UK the moon will have set, but it remains visible throughout the night on Saturday and Sunday, appearing lower in the northern hemisphere sky and higher in the southern hemisphere. The event also revives the “once in a blue moon” expression, though the phrase likely stems from the rarer blue‑tinged moon caused by atmospheric particles.Looking Ahead: When the Next Blue Micromoon Might AppearAccording to Brown, the next UK blue micromoon is projected for 2066, while parts of the US may see one as early as 2053. Until then, enthusiasts can enjoy this once‑in‑a‑few‑decades spectacle.

The northern hemisphere is currently treated to a spectacular view of the constellation Leo, dominating the spring night sky. The Sickle Asterism and Regulus Leo is most easily identified by its distinctive "backwards" question mark, referred to by astronomers as the "sickle" asterism and representing the head of the lion. The constellation's brightest star is Regulus, a brilliant blue-white star that sits almost exactly on the ecliptic, the path traced by the sun, moon and planets across the sky. Historical and Astronomical Significance Antiquity: Recognized since antiquity, it is one of the original 48 constellations listed by Ptolemy in the second century. Star Data: Regulus' position on the ecliptic makes it a critical marker for tracking planetary movements. Visibility: While visible from the southern hemisphere in the northern sky, it is currently the dominant feature in the northern hemisphere's spring evenings. Cultural Legacy Across Civilizations The constellation has a rich mythological tradition that spans thousands of years. In Mesopotamia, it was associated with the lion ridden by the goddess Ishtar, while the ancient Egyptians linked it to the annual flooding of the Nile River, which occurred when the sun passed through this region of the sky. Best Viewing Times for 2026 For optimal viewing, look high in the southern sky. The chart shows the view looking high in the southern sky from London on 27 April at 22:00 BST, although the view will be essentially the same all week.

The Silent Crisis: Why the Imminent Collapse of the Atlantic Current is Being IgnoredThe global climate system is approaching a civilisation-ending tipping point, yet the public remains largely unaware. The Atlantic Meridional Overturning Circulation (Amoc), the oceanic engine that regulates global weather patterns, is facing a reassessment that suggests it is more likely than not to collapse within the next few decades. This event would not merely be a weather anomaly; it would fundamentally alter the habitability of the Northern Hemisphere.The Scientific Reassessment of Amoc StabilityFor decades, the collapse of the Amoc was categorized as a 'high impact, low probability' event. However, recent research has fundamentally shifted this paradigm. Scientists have observed that changes in the temperature and salinity of seawater, driven by climate breakdown, are pushing the system toward a critical threshold.Historical Context: The first paper proposing the system had an 'on' and 'off' state was published in 1961.Current Status: Following the latest reassessment, Prof. Stefan Rahmstorf, a leading authority on the subject, estimates the chances of a shutdown are now 'more than 50%.'Timeline: The tipping point could be reached as early as the middle of this century.Quantifying the Catastrophe: Temperature and Probability DataThe consequences of an Amoc shutdown are not merely theoretical; they are quantifiable and terrifying. Even when accounting for general global heating, the net impact in northern Europe would be a sudden, drastic cooling.European Temperatures: London could see temperatures drop to -19C, Edinburgh to -30C, and Oslo to -48C.Geographic Extent: Sea ice could extend as far south as Lincolnshire in February.Global Impact: Antarctic temperatures could rise by roughly 6C (43F), releasing vast pulses of carbon stored in the Southern Ocean.Global Cascading Effects: From the Amazon to the Southern OceanThe collapse of Amoc would trigger a chain reaction of environmental disasters that would likely be irreversible on a human timescale.Amazon Rainforest: The system delivers heat to the North Atlantic; without it, the Amazon’s water cycles could collapse, tipping the rainforest into a state of cascading failure.US East Coast: There would be an acceleration of sea level rise, threatening major coastal cities.Agriculture: Rain-fed arable agriculture would become impossible almost everywhere in the UK, leading to global food system collapse.Climate Niche: The conditions that sustain human life (the human climate niche) could be rendered uninhabitable across large parts of the globe.The Economic Model of Denial: Billionaires, Flawed Science, and the 'Hothouse Earth' ThreatThe primary reason this catastrophe is not a top priority for governments is the deliberate distortion of climate risk by economic models championed by the ultra-rich. The article argues that oligarchic power has shaped a narrative that bears little relation to scientific reality.Key figures like William Nordhaus, whose 'socially optimal' model suggests a 3.5C-4C rise is acceptable, have been awarded the Nobel Prize for Economics. This model assumes linear impacts and discounts the lives of future generations. Billionaires such as Bill Gates have funded think tanks (like the Copenhagen Consensus Center) run by Bjorn Lomborg, which promote these low-probability models to argue for minimal climate action.This creates a 'billionaire death cult' where a few thousand individuals prioritize short-term wealth accumulation over the survival of billions, effectively steering the world toward a 'hothouse Earth' scenario where very few survive.

The Lyrid meteor shower, active since 16 April, reaches its zenith on the late evening of Wednesday 22 April and the early hours of Thursday 23 April, providing a spectacular display for sky‑watchers across the northern hemisphere. The Lyrid Meteor Shower Peaks This Week Viewing from London, the radiant sits in the constellation Lyra, near the bright star Vega. At 00:01 BST on 23 April the radiant will be visible low in the east, with meteors fanning out in all directions. Viewing Numbers and Timing Maximum rate: ~18 meteors per hour Peak window: late evening of 22 April through the early morning of 23 April Optimal viewing: after midnight, once eyes have adapted for 20‑30 minutes Why the Lyrids Matter to Astronomers Records of the Lyrids date back to 687 BC. Modern science links the shower to comet Thatcher, discovered in 1861. The meteoroids are remnants of the comet’s dust tail, offering a natural laboratory for studying cometary material and atmospheric entry dynamics. What to Expect for Future Lyrid Observations Because the radiant lies low in the northern sky, observers in the southern hemisphere will see a truncated display. In upcoming years, the shower’s intensity is expected to remain steady, but variations in comet Thatcher’s orbit could alter peak rates, making each season a unique observation opportunity.

Experts are closely monitoring climate patterns in the Pacific Ocean, which indicate a high chance of El Niño developing this summer. A strong El Niño event could lead to severe weather conditions, including super-charged rainstorms and droughts, depending on the region. A 'super El Niño' could push 2027 to break global heat records, according to climate scientists. This phenomenon occurs when ocean surface temperatures in the central and eastern tropical Pacific Ocean warm up, leading to significant impacts on global weather patterns. El Niño is characterized by warming of the ocean surface in the central and eastern tropical Pacific Ocean. It's one of three states scientists observe: La Niña, conversely, happens when sea surface temperatures are below average, and neutral conditions are defined when neither El Niño or La Niña are present and surface temperatures are about average. The 'El Niño-southern oscillation' (Enso) tends to develop during spring in the northern hemisphere and shifts every three to seven years. Warming and cooling at sea surface during El Niño and La Niña can range from 1C to 3C, and have enormous effects on precipitation, drought, heat, and climate disasters in different regions. Conditions are currently shifting from La Niña to a neutral pattern, according to the latest outlook from the US Climate Prediction Center. Models show a 62% chance El Niño will emerge this summer and linger until at least the end of the year. A super El Niño that occurred in 2015 brought severe drought in Ethiopia, water supply shortages in Puerto Rico, and smashed records after unleashing a vicious hurricane season in the central North Pacific. A 'super' El Niño means one that is stronger, typically defined by sea surface temperatures spiking up to at least 2C. Noaa scientists have given a 1 in 4 chance that this could happen by fall or winter, with the caveat that spring forecasts are sometimes muddled. Transitions in conditions that happen in the spring can make outcomes a bit harder to predict. Experts warn that a strong or super El Niño could lead to drought and heat across Australia, southern and central Africa, India, and parts of South America. Heavy precipitation, meanwhile, could hit the southern tier of the US, parts of the Middle East, and south-central Asia.

As the northern hemisphere welcomes spring, the constellation of Boötes, the herdsman, is rising to prominence in the eastern sky after dusk. This celestial display is a treat for stargazers, with the constellation's brightest star, Arcturus, shining brightly.A chart showing the view looking east from London at 21:00 BST on 6 April illustrates the optimal viewing conditions. By this time, the darkness is complete, and Arcturus, the fourth-brightest star in the night sky, is easily visible.To locate Boötes, start with the familiar shape of the Plough and follow the curve of its handle downwards in an arc until you reach the orange glow of Arcturus. This method makes it easy to find the constellation in the night sky.Boötes is one of the original 48 constellations defined by Ptolemy in the second century. However, its origins date back thousands of years to ancient Babylon, where it was associated with the god Enlil. In Greek tradition, Boötes is often identified as a herdsman or ploughman, with various mythic tales surrounding his role as a protector of rural life.During this time of year in the northern hemisphere, Boötes rises during twilight and becomes well-placed for observation by late evening. Conversely, from the southern hemisphere, Boötes appears low in the northern sky.
