In 2008, Earth Sent a Message to an Alien Planet with Photos of Celebrities and Politicians. The Signal Will Only Arrive at Its Destination in 2029 — and the Response, If It Comes, Will Not Be Before 2050.

In 2008, Earth sent a message to an alien planet called Gliese 581c. The destination is 21 light-years away, which means the message will only reach the planet in 2029. Even so, any response can only be received, at the earliest, in 2050.

The exoplanet Gliese 581c was discovered in 2007. It is the third planet in the Gliese 581 solar system, which orbits a red dwarf.

It has a mass equivalent to 5.5 times that of Earth. Together with the neighboring planet Gliese 581d, it is outside the so-called habitable zone, but features like cloud cover may open possibilities for the existence of life.

A Project to Search for Alien Life

Based on this slim chance, the “Message from Earth” project was created. The goal was to send a communication signal to verify if there is intelligent life on Gliese 581c.

The message included 501 photos and texts. The images were chosen by the public through the old social networking site Bebo. The initiative was organized by the Ukrainian Space Agency.

Among the faces sent to the aliens were former president Barack Obama, actress Gillian Anderson, singer Cheryl Cole, and politician Hillary Clinton.

The Long Wait for a Response

Even if the aliens are at home and able to understand what we sent, we should not expect a response before 2050. It will take 21 light-years to go and another 21 light-years to come back.

Now, we can only hope that the inhabitants of Gliese 581c are not offended by the photos and

The Long Wait for a Response

A Chinese factory in Guangdong is assembling a humanoid robot every 30 minutes while Tesla, Figure, and Boston Dynamics still struggle to deliver 10 thousand per year.

Seven world powers including the US, China, and Russia are spending €22 billion on a reactor in the south of France that aims to confine plasma at 150 million degrees Celsius, ten times the temperature of the Sun’s core, using a magnetic field capable of lifting an entire aircraft carrier.

Secret chamber sealed 4,500 years ago found in the Pyramid of Khufu, and Hawass announces its opening to the world in 2026

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

While communities suffer from water scarcity and the advancing desert, women in Morocco use nets high up in the mountains to trap fog droplets, fill reservoirs, and transport drinking water through more than 10 km of piping.

China has begun the second phase of energy assistance to Cuba with a 120 MW solar generation plan, and the first result is a photovoltaic park with batteries that regulates voltage, controls frequency, and provides local autonomy to an island suffocated by chronic blackouts.

Germany installed vertical solar panels on a lake in Bavaria, and the result broke conventional logic: instead of producing energy at midday peak, the plant generates more early in the morning and in the evening, exactly when families turn on appliances and factories are in full swing.

Cell phones up to R$ 3,000 can run heavy games, record in 8K, and last for years, but only a few models truly deliver all of this.

Couple faces snow, ice, ferry, and 14 countries on a 33,800 km journey with an electric car, from the Magnetic North Pole to the South Pole, making history on wheels.

Audi launches new Q3 2027 for nearly R$ 400,000 in Brazil and makes it clear that its true target is still BMW and Mercedes-Benz

While giant ships need depth to enter loaded, Suape deepens the external channel to 20 meters, allowing Suezmax tankers of up to 175,000 tons and turning an invisible work at the bottom of the sea into a logistical advantage for fuels.
