Just as the flowers have now blossomed, the skies are also in full bloom this spring. This month of April is abundant in astronomical events that are worthy of celebration like the sakura.

Two of these astronomical events have already passed (both occurred on April 1), but there are still eight more to look forward to. Without further ado, here are the nighttime sky phenomena you have to watch out for:

April 6 – Leo the Lion’s Heart Gets Up Close and Personal With the Moon

On the night of the sixth, the heart of the constellation Leo (called Regulus), will only be one degree away from Luna. To best see the blue-white heart of the lion and its closeness with the moon, cover the moon’s disc with your thumb. That way, the glare is cut off and you will better see the distinctive reverse question mark sign of Leo’s front.

April 7 – Jupiter Lights Up the Sky

Just a day after the gibbous moon passes by Leo’s heart, Jupiter will light up the sky with its celestial brightness. This is because Jupiter will be sitting exactly opposite of the sun, letting it bask in the solar light. Thanks to that, the planet will be at its brightest and largest for the year on April 7.

April 10 – Luna Joins Jupiter

Two nights after this, Jupiter will also have another moment as its moons will cast large shadows on its face. However, that is not the last sky event that features the planetary version of the supreme god of Rome. On April 10, the planet will continue to reign in the night sky as a full moon graces the heavens with it. At the same time, the two celestial bodies will also edge closer to Spica. This makes three astronomical events for Jupiter this April.

April 16 – Moon Glides By Saturn

For those who have difficulty spotting Saturn in the sky, watch out for this astronomical event as the moon will help you out. However, this will happen in the wee hours of morning just before dawn, so you either have to stay up later or wake up really early in time for this to happen.

But for patient stargazers armed with even the smallest telescope, Saturn will show off its rings. On top of that, it might even offer a glimpse of its moons.

April 22 – Mars Guides the Eye to Pleiades

The Red Planet will begin its descent in the western sky as early as April 17. Thanks to its movement, it will draw close to the cluster of stars called the Pleiades or the Seven Sisters. But the peak of this celestial event will be on the 22nd when they align close to each other at the same spot in the sky.

April 22 – Lyrid Meteor Shower Peak

Although the Lyrid meteor shower is active annually for a week or so around April 16 – 25, this year the astronomical event will peak on the morning of April 22. So if you want to catch the short bursts of falling stars, you have to stay up late on the night of the 21st. And if you want to see the bulk of the shower, you have to keep your eyes peeled until a few hours before sun-up. Fortunately, the waning crescent moon will not rain on the meteors’ parade.

April 23 – Venus Sidles Beside Luna

Venus the Morning Star will align beside the moon in the early morning of April 23. Stargazers are advised to use binoculars to better see Venus and the moon hang in the sky beside each other. Also, the best time for this would be 45 minutes before the sun goes up.

April 28 – Aldebaran and the Moon Meet Again

Aldebaran and the moon will cozy up with each other for the second time in April on the 28th (the first time was on the 1st). Taurus’ brightest star and the earth’s satellite next encounter will bring them much closer to each other. At this point, they will only be half a degree apart from each other.

That’s not all, though. There is an astronomical event called lunar occultation, when Aldebaran goes behind the moon, that lucky stargazers in Europe, North America, and North Africa will witness. Times vary across continents so you have to check out this table to find out what time you should peep at the sky.

So, which one of these astronomical events are you most excited for?

Archaeology and anthropology consume my life, but hey! I like to read and write about tech, science, and geeky stuff too.

What is the most terrifying communication that humanity could receive from outer space?

If there are extraterrestrial civilizations within a reasonable distance capable of detecting our unintentional transmissions, there exists a possibility, albeit small, that among the initial signals they intercept, they could receive the commencement of the 1936 Olympic Games. Therefore, in the unlikely event that they do receive these signals, we might come across a speech by Adolf Hitler during our first encounter with an alien species.

“Naturally, this was not the initial transmission,” clarified Seth Shostak, a senior astronomer at SETI, during an interview with RealClearScience. “However, it was emitted at a sufficiently high frequency to penetrate the ionosphere.”

In the movie Contact, this ultimately became the initial communication that mankind received from an extraterrestrial society. The entities promptly returned the signal to Earth, unaware of the profound consequences that transmitting broadcasts of Adolf Hitler from outer space would have on the targeted species they were endeavoring to establish communication with. It is similar to greeting a random person and then unintentionally reciting a chapter from Mein Kampf.

Fortunately, it is highly likely that we won’t encounter this issue because extraterrestrial civilizations shouldn’t be able to distinguish the signal strengths.

“The power consumption would have been minimal, and the antenna used would not have had a specific direction,” Shostak elaborated. “The notion that extraterrestrial beings might intercept it is highly improbable.”

However, it is possible that we may receive significantly more alarming initial communications, as individuals have been deliberating on X (Twitter) and Reddit.

It appears that people are primarily focused on receiving warnings from extraterrestrial civilizations right now, possibly as a result of a recent unnamed television series.

According to certain proposed resolutions to the Fermi Paradox, which ask why we haven’t detected any signs of advanced extraterrestrial civilizations, the explanation is that these civilizations are intentionally concealing their presence due to the apprehension of their own annihilation.

Another concern is the possibility of receiving an unclear message that extraterrestrial beings will provide us with limited information, apart from the fact that they are en route.

One theory, called the Zoo Hypothesis, is related to this topic. The theory posits that extraterrestrial beings possess knowledge of our existence but deliberately confine us within a designated “zoo” to allow for our evolutionary and societal development. This parallels humanity’s practice of preserving certain areas as nature reserves and refraining from engaging with uncontacted tribes. Based on this hypothesis, it is possible that we may receive contact once we have reached a satisfactory level of technological and societal development and potentially be accepted into a community of other galaxies.

Although there is a prevailing apprehension that initiating communication with an extraterrestrial civilization will probably elicit fear due to humanity’s historical tendency to fear the unfamiliar, there is a potentially more alarming notion.

Orbex’s recent funding could expedite the launch of its Prime microlauncher into space

Orbex, a small launch company based in the UK, got more money from backers, including Scotland’s national bank. The company is now getting ready for its first orbital launch, but the date for that mission has not yet been set.

With its start in 2015, Orbex is one of only a few companies in Europe racing to make the next generation of launch vehicles. The retirement of the Ariane 5 and big delays to the Ariane 6 and Vega C rockets have left a huge gap that these companies are trying to fill. Without these vehicles, there is almost no native launch capacity coming out of Europe.

But Orbex also has a chance because of his absence. The company is working on what is sometimes called a “microlauncher.” It is a two-stage vehicle called Prime that is only 19 meters tall and can take up to 180 kilograms of payload. Rocket Lab’s Electron is the most similar. It’s only a meter shorter, but it can take up to 300 kilograms.

The fact that Orbex is small is not a problem for the company. In fact, Orbex CEO Philip Chambers told TechCrunch via email that the company is seeing “positive market conditions” for its product.

“There is a pent-up demand for sovereign launch capabilities,” he said. “We are seeing an exponential growth of satellites being launched into LEO, and demand for launch is far exceeding supply. At the moment, it’s not possible to launch a single kilogram from Europe.” “We will let European customers choose how to launch their own payloads and let them launch European payloads from European soil.”

Prime will take off from a new spaceport being built with money from the UK’s national space agency in Sutherland, which is in northern Scotland. The end goal is to use a patented recovery technique that the company calls REFLIGHT. This is an interstage device that sits between the rocket stages. When the booster comes off, four “petals” will unfold and, along with a parachute, create enough drag for a soft landing in the ocean.

It’s possible that a bigger car will be made in the future, but Chambers made it clear that Prime was the company’s top goal. He did say, though, that many of the rocket’s main technologies could be used with bigger packages.

Considering the laws of physics, it would be logical for Orbex to explore the option of using larger vehicles in order to compete on cost per kg.

The company is starting its Series D round with £16.7 million ($20.7 million) in new funding, including investments from Octopus Ventures, BGF, Heartcore, EIFO, and other contributors. Following the closure of a £40.4 million ($50 million) Series C in October 2022, Orbex has secured additional capital. Although a spokesperson has confirmed that the new funding will assist Orbex in accelerating the development of Prime, ensuring its readiness and scalability for the launch period, the specific launch window has not been announced yet.

The Ingenuity team at NASA has received their last communication, however, the Mars helicopter is still operational

The NASA Ingenuity team said goodbye to the helicopter robot and got one last message before splitting up. But ingenuity isn’t really dead yet; it will still be collecting data on Mars.

It’s a great little robot, and in April 2021, it was the first to fly powered and controlled on a planet other than Earth. That’s not easy to do because conditions on Mars are so different.

“The Red Planet has a much lower gravity—one-third that of Earth’s—and an extremely thin atmosphere with only 1% of Earth’s pressure at the surface,” NASA said in a press release after Ingenuity’s first flight. “This means there are relatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can interact to achieve flight.”

It was planned for the helicopter, which was really just a prototype, to make five flights over 30 days on Mars. Instead, it made 72 flights over 1,000 days. NASA started to use it to get a bird’s-eye view of Mars and find interesting places for Perseverance to go back and look at more closely.

On the 72nd flight, unfortunately, Ingenuity had to make an emergency landing and lost touch with Perseverance. When they got in touch again, pictures from the helicopter showed that a rotor was badly damaged, so Ingenuity would not be able to fly again.

Even though the helicopter can’t fly anymore, it can still gather information and send it to Perseverance. Perseverance then sends the information to Earth through NASA’s Deep Space Network. Before the Ingenuity team broke up, they got one last message from Ingenuity and ate cake to celebrate.

“I’m sorry, Dylan Thomas, but Ingenuity will not be going gently into that good Martian night,” said Josh Anderson, lead of the Ingenuity team at JPL. “It’s hard to believe that she still has something to give after more than 1,000 days on Mars’ surface, 72 flights, and one rough landing.” Because of how hard this amazing team worked, not only did Ingenuity do better than we thought it would, but it may also teach us new things in the years to come.

After stopping in “Valinor Hills” to rest, the robot’s job will be to gather data while it’s still, hopefully learning useful things about the planet’s environment before future missions with people.
