The report provided by the Office of the Director of National Intelligence investigates the potential threat of unidentified aerial phenomena (UAP).

There are many interesting points to bring up in the 9-page document, but for the purpose of this article we will concentrate purely on why the US government didn't confirm the existence of aliens. After reading through the document you can understand that the Unidentified Aerial Phenomena Task Force (UAPTF) simply doesn't have enough data to confirm or rule out the possibility of extraterrestrial life.

The UAPTF mainly concentrated on reports from military aviators and found that the data provided to them had large variability, with minimal patterns. Essentially the dataset was too small. The patterns that were noticed regarded the size of a UAP, shape, and particularly its method for propulsion. The document goes on to state that there are probably multiple explanations for these UAPs, as not all of them are the same which means they require different explanations.

The highly anticipated report from the Office of The Director of National Intelligence regarding UFO sightings by military personel has been released.

June 25 has arrived and the Pentagon report ordered to be presented to the Senate regarding UFOs, or as outlined in the document, UAPs (Unidentified Aerial Phenomena). The document has been unclassified and free for public viewing here. Under a section in the document states that there are 18 incidents described in 21 reports that a UAP performed unusual movement patterns of flight characteristics that may have demonstrated the use of advanced technology.

The report reads, "Some UAP appeared to remain stationary in winds aloft, move against the wind, maneuver abruptly, or move at considerable speed, without discernable means of propulsion. In a small number of cases, military aircraft systems processed radio frequency (RF) energy associated with UAP sightings." The Unidentified Aerial Phenomena Task Force (UAPTF) currently holds a small amount of data that isn't enough to confirm if its valid or not, rendering the reporting largely inclusive, according to the report.

A new space race may have just begun as China has announced they will be sending the first humans to land on Mars.

The ambitious plans were announced by Wang Xiaojun, the head of the state-owned China Academy of Launch Vehicle Technology (CALT). Xiaojun made the announcement at the Global Space Exploration Conference (GLEX 2021) where he gave a speech called "The Space Transportation System of Human Mars Exploration". China has its eyes set on Mars, and the nation plans on getting humans there in three stages.

The first stage will see the country send robots to the surface of the Red Planet to collect samples and then return back to Earth. These robots would also be tasked with finding a suitable base site for when humans land. The second stage will feature humans being sent there to build a permanent settlement. The last state includes large-scale Mars to Earth cargo trips that will include cargo from Earth being shipped to Mars and cargo from Mars being shipped back to Earth.

When NASA's Hubble Space Telescope is online and working it can produce some shocking images of the cosmos, and this is no exception.

The image seen above taken by Hubble is of NGC 1052-DF2, or DF2. This galaxy, in particular, continues to perplex astronomers as estimates show that it lacks any dark matter, which is an "invisible form of matter that provides the gravitational glue to hold galaxies together" according to NASA. The team behind the discovery has published their findings in The Astrophysical Journal Letters.

The researchers found that DF2 is actually 72 million light-years which is more than most astronomers previously estimated at 42 million light-years. Pieter van Dokkum of Yale University says that DF2 is a cosmic cotton ball that is a "see-through galaxy" that features stars spread out. The diameter of DF2 is almost as large as our galaxy, but DF2 only contains 1/200th of the amount of stars as the Milky Way.

The scenario proposed sounds impossible, but it's actually quite real. NASA's Chandra X-ray Observatory has the images to prove it.

So, what are we exactly looking at here? The above image clearly shows a "hand", but it's not a galactic being of any kind, it's the remnants of a massive star dying in a supernova explosion. What appears in the image in the shape of a hand is what is known as a pulsar, an extremely dense corpse of what was once a large star.

The pulsar in the image named MSH 15-52 has many energetic particles surrounding it, and those energetic particles combined with the debris left over from the explosion have created the glorious image of a hand reaching for something. That "something" is an enormous gas cloud called RCW 89. The ghostly "hand" is located 17,000 light-years away from Earth, and according to astronomers, the light emitted from the supernova explosion would have reached Earth around 1,700 years ago, making MSH 15-52 one of the youngest supernova explosions we have found in the Milky Way galaxy.

The first humans that land on Mars to begin colonizing the red planet will be faced with several life-threatening issues.

The main issues for colonizers are that planets lack of atmosphere, extreme weather, extreme temperatures, radiation, and humans would be experiencing a different amount of gravity than their bodies are used to. Another problem that isn't readily discussed is the issue with space debris colliding with Mars. Due to Mars having less than 1% of Earth's atmosphere, space debris such as meteors don't tend to break up when they are entering Mars' atmosphere.

In fact, most space debris make it to the surface, causing impact craters, which is something that usually doesn't happen on Earth. A 2013 study estimated that Mars sees as many as 200 small asteroids reach its surface, causing impact craters of at least 12.8 feet in diameter. If humans began colonizing Mars with settlements, you can understand the catastrophe that would fall upon the settlement if even one of these meteors struck it.

The Hubble Space Telescope has been in operation for more than 30 years, and it still continues to shock onlookers of what it can produce. But, what will Hubble's successor be able to do?

The James Webb Space Telescope (JWST) has been dubbed as Hubble's successor, and its launch has been highly anticipated for quite some time. Unfortunately, many delays occurred due to construction setbacks as well as COVID-19. However, when JWST is finally launched, it will give astronomers the opportunity to view the universe in its baby stages, just less than 800 million years old.

The JWST will literally be able to look back in time, and astronomers are planning on its extremely sensitive low-light instruments to peer at distant quasars. A good way to understand this is the light that Webb is absorbing has taken billions of years to reach it, allowing for astronomers to see things how they were billions of years ago and not how they are today. Astronomers' ability to see back to the early stages of the universe paves the way for a deeper understanding of how galaxies evolve, supermassive black hole formations, and evolution in general.

If you happened to miss the Blood Supermoon that recently occurred, now if you chance to catch the last supermoon of 2021, the Strawberry Moon.

According to Farmer's Almanac, the Strawberry Moon will be visible this coming Thursday, June 24, until June 26. What is a super moon? The definition of super moon is given to the moon when its orbit brings it closest to Earth. Due to the orbit of the moon, this only happens a few times a year, and as explained by Almanac, a full moon that is less than 224,000 miles away from Earth is considered a super moon.

The coming Strawberry Moon will be located just outside the cut-off line, being 224,662 miles away from Earth. However, due to this month's supermoon only being a few thousand miles further back than April and May's supermoons, onlookers at the cosmic spectacle shouldn't see any noticeable difference. Additionally, the name "Strawberry Moon" wasn't derived from the hue that it can produce, but instead, it comes from Algonquin, Ojibwe, Dakota, and Lakota Native American tribes as it marks the ripening of June strawberries.

Humans have only just begun our search for alien life out in the cosmos, but have we considered that alien life is already spying on us, and we don't even know it?

A recent study published by a team of astronomers explores this question as they have identified 1,715 stars within 300 light-years of Earth that could view Earth if they had the technology. These nearly 2,000 stars could have been watching Earth for the last 5,000 years. A form of planetary detection is the transit method, and it involves an astronomer viewing and recording the reduction of light from a host star. When an astronomer notices a reduction in the star's brightness, they know an exoplanet is passing by.

While this method of planetary detection is effective and efficient, astronomers can only view exoplanets on Earth's orbital plane, or more simply, within our line of sight. This means that astronomers aren't able to see the exoplanets that aren't "edge-on" to us. Additionally, aliens that are using this same method could also be viewing us and performing the same mathematical estimations of our planet.

There is a very large object that is moving outside of our solar system, but it will soon enter Saturn's orbit, according to astronomers.

The very large object is a comet named 2014 UN271, and back in 2013, it was first officially discovered by the Dark Energy Survey, which is a collaborative project that has a goal of mapping galaxies and unlocking more knowledge into dark energy. The discovery by DES was just announced on June 13, and now astronomers are speculating that the rock could be as big as a small dwarf planet with an estimated diameter of anywhere around 80 to 229 miles.

Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, questioned the assumption that 2014 UN271 is as big as a dwarf planet, saying, "Seems like maybe a tad too small to qualify as dwarf planet? Very cool nevertheless." Foxnews reports that the comet will enter our solar system within the next decade, coming close to Saturn's orbit.
